Description Introduction about IC parts 74LVX161284A
The electronic components LVX161284A contains eight bidirectional data buffers and eleven control/status buffers to implement a full IEEE 1284 compliant interface. The device supports the IEEE 1284 standard, with the exception of output slew rate,and is intended to be used in an Extended Capabilities Port mode (ECP). The pinout allows for easy semiconductor connection from the Peripheral (A-side) to the Host (cable side).
Outputs on the cable side can be configured to be either open drain or high drive (± 14 mA) and are connected to aseparate power supply pin (VCCcable) to allow these outputs
to be driven by a higher supply voltage than the A-side. The pull-up and pull-down series termination resistance of these outputs on the cable side is optimized to
drive an external cable. In addition, all inputs (except HLH) and outputs on the cable side contain internal pull-up resistors connected to the VCCcable supply to provide proper termination and pull-ups for open drain mode.

Description about electronic components MAX6950/MAX6951
The electronic components MAX6950 and electronic component MAX6951 are compact common-cathode display drivers that interface microprocessors to individual 7-segment numeric LED digits, bar graph, or discrete LEDs through an SPI™-, QSPI™-MICROWIRE™- compatible serial interface. The supply voltage can be as low as 2.7V.
The MAX6950 drives up to five 7-segment digits or 40 discrete LEDs. The ic components MAX6951 drives up to eight 7-segment digits or 64 discrete LEDs.
Included on-chip are hexadecimal character decoders (0–9, A–F), multiplex scan circuitry, segment and digit drivers, and a static RAM that stores each digit. The
user may select hexadecimal decoding or no-decode for each digit to allow any mix of 7-segment digits, bar graph, or discrete LEDs to be driven. The segment current
for the LEDs is set by an internal digital brightness control. The segment drivers are slew-rate limited to reduce EMI.
Individual digits may be addressed and updated without rewriting the entire display. The devices include a low-power shutdown mode, digital brightness control, a scan-limit register that allows the user to display from one to eight digits, segment blinking that can be synchronized across drivers, and a test mode that forces all LEDs on.

The General Description of electronic components LM741
The information electronic components LM741 comes from hqew.net,supply ICs , Semiconductors,Capacitors, Inductors, Quartz Crystal Devices,Resistors,Connectors,Switches,LEDs,Wires , Cables and so on
The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements
for the 709C, LM201, MC1439 and 748 in most applications.
The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded,
as well as freedom from oscillations.
The LM741C is identical to the ic components LM741/LM741A except that the electronic component LM741C has their performance guaranteed over a 0°C to +70°C temperature range, instead of 55°C to +125°C.

Many features of Ic components LM101A/LM201A/LM301A
This Series of electronic components offers many features which make its application nearly foolproof:
overload protection on the input and output, no latch-up when the common mode range is
exceeded, and freedom from oscillations and compensation with a single 30 pF capacitor. It has advantages over internally compensated amplifiers in that the frequency
compensation can be tailored to the particular application.
For example, in low frequency circuits it can be overcompensated for increased stability margin. Or the compensation can be optimized to give more than a factor of
ten improvement in high frequency performance for most applications.

Do you know the 10A 1-30V Variable Power Supply with LM317?
About the Variable Power Supply with LM317,do you know?
Here is a simple and economical 10A variable power supply with 1.2-30V. LM317 have been used to drive 3 NPN TIP41C transistors (or three 2N3055). Nothing to say about the project, it is really simple. The main supply must be connected to a rectified source (transformer + 20-30A bridge rectifier). For Q1,2 and 3 can be used any power TO220 transistor (TIP132C,TIP41C etc) or three external 2N3055 transistors.
There are many ic components such as lm358,ne555,lm339 beside LM317,those are top electronic components,the electronic company develops very quickly now,so the need of hot
ic components model is become more.
Here is a simple and economical 10A variable power supply with 1.2-30V. LM317 have been used to drive 3 NPN TIP41C transistors (or three 2N3055). Nothing to say about the project, it is really simple. The main supply must be connected to a rectified source (transformer + 20-30A bridge rectifier). For Q1,2 and 3 can be used any power TO220 transistor (TIP132C,TIP41C etc) or three external 2N3055 transistors.

electronic components lm358 General knowledge Description
Introduction ic components lm358 Low Power Dual Operational Amplifiers,many book about the electronic components detailed introduced.
The Ic components LM158 series consists of two independent, high gain,internally frequency compensated operational amplifierswhich were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
If you learn more about ic components, recommend a site hqew.net, electronic components trading platform,many hard to find besides lm358 on hqew.net. top b2b marketplace of electronic components.

Introduction to the function about LED - Light Emitting Diode
LED - Light Emitting Diode is One of the electronic components,here the function about LED - Light Emitting Diode:
1.An LED is a diode that emits or gives out light when current flows through it.
2.LEDs are used in electrical appliances (e.g. the red on-off light on a TV) to show that they are switched on.
