54ACT825
8-Bit D Flip-Flop
General Description
The ’ACT825 is an 8-bit buffered register. They have Clock
Enable and Clear features which are ideal for parity bus in-
terfacing in high performance microprogramming systems.
Also included are multiple enables that allow multi-use con-
trol of the interface. The ’ACT825 has noninverting outputs
and is fully compatible with AMD’s Am29825.
