74ACT18823 18-Bit D-Type Flip-Flop with 3-STATE Outputs
General Description
The ACT18823 contains eighteen non-inverting D-type flipflops 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
