54ACT823
9-Bit D Flip-Flop
TRI-STATE outputs for bus interfacing
Inputs and outputs are on opposite sides
ACT823 has TTL-compatible inputs
General Description
The ACT823 is a 9-bit buffered register. It features Clock En-
able and Clear which are ideal for parity bus interfacing in
high performance microprogramming systems. The ACT823
offers noninverting outputs and is fully compatible with
AMD’s Am29823.
