74LVXZ161284B Datasheet

Supports IEEE 1284 Level 1 and Level 2 signaling standards for bidirectional parallel communications between personal computers and printing peripherals
Translation capability allows outputs on the cable side to interface with 5V signals
All inputs have hysteresis to provide noise margin
B and Y output resistance optimized to drive external cable
B and Y outputs in high impedance mode during power down
C inputs and B, Y outputs on cable side have internal 1.4 kohm pull-up resistors
Flow-through pin configuration allows easy interface between the "Peripheral and Host"
Replaces the function of two (2) 74ACT1284 devices
Power-up protection prevents errors when the printer is powered on but no valid signal is at the input pins (A₉- A₁₃).
