Octal D-Type Flip-Flop with 3-state Output

TC74AC374P/F/FT Non-Inverting

TC74AC534P/F Inverting

The TC74AC374 and TC74AC534 are advanced high speed
CMOS OCTAL FLIP-FLOPS fabricated with silicon gate and
double-layer metal wiring C

They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.

These 8-bit D-type flip-flops are controlled by a clock input
(CK) and a output enable input (

impedance state.

The TC74AC374 has non-inverting outputs, and TC74AC534
has inverting outputs.

All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
