The MC74VHCT74A is an advanced high speed CMOS D–type flip–flop
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
The signal level applied to the D input is transferred to Q output during the
positive going transition of the Clock pulse.
Reset (RD) and Set (SD) are independent of the Clock (CP) and are
accomplished by setting the appropriate input Low.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
The VHCT inputs are compatible with TTL levels. This device can be used
as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS
level output swings.
The VHCT74A input structures provide protection when voltages between
0V and 5.5V are applied, regardless of the supply voltage. The output
structures also provide protection when VCC=0V. These input and output
structures help prevent device destruction caused by supply voltage –
input/output voltage mismatch, battery backup, hot insertion, etc.
