54ACT564
Octal D-Type Flip-Flop with TRI-STATE® Outputs
General Description
The ’ACT564 is a high-speed, low power octal flip-flop with a
buffered common Clock (CP) and a buffered common Out-
put Enable (OE). The information presented to the D inputs
is stored in the flip-flops on the LOW-to-HIGH Clock (CP)
transition.
The ’ACT564 is functionally identical to the ’ACT574, but
with inverted outputs.
Features
n ICC and IOZ reduced by 50%
n Inputs and outputs on opposite sides of package
allowing easy interface with microprocessors
n Useful as input or output port for microprocessors
n Functionally identical to ’ACT574 but with inverted
outputs
n TRI-STATE outputs for bus-oriented applications
n Outputs source/sink 24 mA
n ’ACT564 has TTL-compatible inputs
n Standard Microcircuit Drawing (SMD) 5962-89557
