General Description

The ACT16543 contains sixteen non-inverting transceivers containing two sets of D-type registers for temporary storage of data flowing in either direction. Each byte has separate control inputs which can be shorted together for full 16-bit operation. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent input and output control in either direction of data flow.

Features

■ Independent registers for A and B buses

■ Separate controls for data flow in each direction

■ Back-to-back registers for storage

Multiplexed real-time and stored data transfers

■ Separate control logic for each byte

■ Outputs source/sink 24 mA

■ TTL-compatible inputs
