Dual D-Type Flip Flop with Preset and Clear
The TC74HCT74A is a high speed CMOS D FLIP FLOP
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.
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.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
