Dual D-Type Flip Flop with Preset and Clear

The TC74HCT74A is a high speed CMOS D FLIP FLOP

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

This device 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.

The signal level applied to the D INPUT is transferred to Q

OUTPUT during the positive going transition of the CLOCK

pulse.

CLEAR and PRESET are independent of the CLOCK and

are accomplished by setting the applopriate input to an “L” level.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 74LS74

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.
