The MC74VHCT574A is an advanced high speed CMOS octal flip–flop
with 3–state output fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.
This 8–bit D–type flip–flop is controlled by a clock input and an output
enable input. When the output enable input is high, the eight outputs are in a
high impedance state.
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 VHCT574A input and output (when disabled) structures provide
protection when voltages between 0V and 5.5V are applied, regardless of
the supply voltage. These input and output structures help prevent device
destruction caused by supply voltage – input/output voltage mismatch,
battery backup, hot insertion, etc.

• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
• Chip Complexity: 286 FETs or 71.5 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
