74ACT18823

18-Bit D-Type Flip-Flop with 3-STATE Outputs

General Description

The ACT18823 contains eighteen non-inverting D-type flip-

flops with 3-STATE outputs and is intended for bus oriented

applications. The device is byte controlled. A buffered clock

(CP), Clear (CLR), Clock Enable (EN) and Output Enable

(OE) are common to each byte and can be shorted

together for full 18-bit operation.

Features

s Broadside pinout allows for easy board layout

s Separate control logic for each byte

s Extra data width for wider address/data paths or buses

carrying parity

s Outputs source/sink 24 mA

s TTL-compatible inputs
