TC74HCT574AP,TC74HCT574AF
Octal D-Type Flip-Flop with 3-State Output
The TC74HCT574A is a high speed CMOS OCTAL FLIP-FLOP
with 3-STATE OUTPUT fabricated with silicon gate C
2
MOS
technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Its inputs are compatible with TTL, NMOS, and CMOS output
voltage levels.
Its 8-bit D-type flip-flops is controlled by a clock input (CK)
and an output enable input (
OE
).
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
