MC74HC374A/D
MC74HC374A
Octal 3-State Non-Inverting
D Flip-Flop
HighPerformance SiliconGate CMOS
The MC74HC374A is identical in pinout to the LS374. 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 flipflops, but when Output Enable is high, the outputs are forced
to the highimpedance state; thus, data may be stored even when the
outputs are not enabled.
The HC374A is identical in function to the HC574A which has the
input pins on the opposite side of the package from the output. This
device is similar in function to the HC534A which has inverting
outputs.
