D-TYPE FLIP FLOP WITH PRESET AND CLEAR
The TC7WH74 is an advanced high speed CMOS D-FLIP
FLOP fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
The signal level applied to the D INPUT is transferred to
Q OUTPUT during the positive going transition of the CK
pulse.
CLR and PR are independent of the CK and are
accomplished by setting the appropriate input low.
An input protection circuit ensures that 0 to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
system and two supply systems such as battery back up.
This circuit prevents device destruction due to
mismatched supply and input voltages.
