High–Performance Silicon–Gate CMOS
The MC54/74HC574A is identical in pinout to the LS574. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
Data meeting the setup time is clocked to the outputs with the rising edge
of the Clock. The Output Enable input does not affect the states of the
flip–flops, but when Output Enable is high, all device outputs are forced to
the high–impedance state. Thus, data may be stored even when the outputs
are not enabled.
The HC574A is identical in function to the HCT374A but has the flip–flop
inputs on the opposite side of the package from the outputs to facilitate PC
board layout.
The HC574A is the noninverting version of the HC564.
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
