3 TO 8 LINE DECODER INVERTING

74ACT138 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

74ACT138 General 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). .
