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 (VCCcable) 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 VCCcable supply to provide  proper termination and pull-ups for open drain mode.

Detailed info about electronic component OP1177 series

The electronic component OPx177 family consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consump-tion. Outputs are stable with capacitive loads of over 1000 pF with no external compensation. Supply current is less than 500 μA per amplifier at 30 V. Internal 500 Ω series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal.

Unlike previous high voltage amplifiers with very low offset voltages, the electronic components OP1177 (single) and OP2177 (dual) amplifiers are available in tiny 8-lead surface-mount MSOP and 8-lead narrow SOIC packages. The OP4177 (quad) is available in TSSOP and 14-lead narrow SOIC packages. Moreover, specified performance in the MSOP and the TSSOP is identical to performance in the SOIC package. MSOP and TSSOP are available in tape and reel only.
