Additional preview pages of the 74VHC161284 datasheet.

The VHC161284 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 and is intended to be used in Extended Capabilities Port mode (ECP).

s Supports IEEE 1284 Level 1 and Level 2 signaling standards for bidirectional parallel communications between personal computers and printing peripherals s Replaces the function of two (2) 74ACT1284 devices s All inputs have hysteresis to provide noise margin s B and Y output resistance optimized to drive external cable s B and Y outputs in high impedance mode during power down s Inputs and outputs on cable side have internal pull-up resistors s Flow-through pin configuration allows easy interf.
