74AC574 • 74ACT574
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The AC/ACT574 is a high-speed, low power octal flip-flop
with a buffered common Clock (CP) and a buffered com-
mon Output Enable (OE). The information presented to the
D-type inputs is stored in the flip-flops on the LOW-to-HIGH
Clock (CP) transition.
The AC/ACT574 is functionally identical to the AC/ACT374
except for the pinouts.
Features
s I_CC and I_OZ reduced by 50%
s Inputs and outputs on opposite sides of package
allowing easy interface with microprocessors
s Useful as input or output port for microprocessors
s Functionally identical to AC/ACT374
s 3-STATE outputs for bus-oriented applications
s Outputs source/sink 24 mA
s ACT574 has TTL-compatible inputs
