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.
Features
n Outputs source/sink 24 mA
n Inputs and outputs are on opposite sides
n ’ACT825 has TTL-compatible inputs
n Standard Microcircuit Drawing (SMD)
— ’ACT825: 5962-91611

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recom-
mend operation of FACT™ circuits outside databook specifications.
