Product details

Description

The 74ACT1284 contains four non-inverting bidirectional buffers and three non-inverting buffers with open Drain outputs and high drive capability on the B Ports.

It is intended to provide a standard signaling method for a bi-direction parallel peripheral in an Extended Capabilities Port mode (ECP).

Features

s TTL-compatible inputs s A Ports have standard 4 mA totem pole outputs s Typical input hysteresis of 0.5V s B Port high drive source/sink capability of 14 mA s Bidirectional non-inverting buffers s Supports IEEE P1284 Level 1 and Level 2 signaling standards for bidirectional parallel communications between personal computers and printing peripherals s B Port outputs in High Impedance mode during power down s Guaranteed 4000V minimum ESD protection Ordering Code: Order Number 74ACT1284SC 74ACT1.
