Description

The MM74HC245ASJX 3-STATE bidirectional buffer utilizes advanced silicon-gate CMOS technology, and is intended for two-way asynchronous communication between data buses. It has high drive current outputs which enable high speed operation even when driving large bus capaci-tances. This circuit of MM74HC245ASJX possesses the low power consumption and high noise immunity usually associated with CMOS cir-cuitry, yet has speeds comparable to low power Schottky TTL circuits.

This MM74HC245ASJX has an active LOW enable input G  and a direc-tion control input, DIR. When DIR is HIGH, data flows from the A inputs to the B outputs. When DIR is LOW, data flows from the B inputs to the A outputs. The MM74HC245ASJX transfers true data from one bus to the other.

This MM74HC245ASJX can drive up to 15 LS-TTL Loads, and does not have Schmitt trigger inputs. All inputs are protected from damage due to static discharge by diodes to V_CC  and ground.
