General Description

The VHC74 is an advanced high speed CMOS Dual

D-Type 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 the Q output during the posi-

tive 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 0V 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

systems and two supply systems such as battery

backup. This circuit prevents device destruction due to

mismatched supply and input voltages.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.

All packages are lead free per JEDEC: J-STD-020B standard.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions

(2)

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to absolute maximum ratings.

Note:

2. Unused inputs must be held HIGH or LOW. They may not float.
