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.
