TC74ACT574P, TC74ACT574F, TC74ACT574FT
Octal D-Type Flip-Flop with 3-State Output
The TC74ACT574 is an advanced high speed CMOS OCTAL
FLIP-FLOP fabricated with silicon gate and double-layer metal
wiring C

MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This devices may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levels.
These 8-bit D-type flip-flops are controlled by a clock input
(CK) and a output enable input (
OE
).
When the
OE
input is high, the eight outputs are in a high
impedance state.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
