74VHCT74A

Dual D-Type Flip-Flop with Preset and Clear

General Description

Features

The VHCT74A is an advanced high speed CMOS Dual

D-Type Flip-Flop fabricated with silicon gate CMOS tech-

nology. 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

positive going transition of the CK pulse. CLR and PR are

independent of the CK and are accomplished by setting the

appropriate input LOW.

■ High speed: f_MAX160 MHz (typ) at T_A25 C

■ High noise immunity: V_IH2.0V, V_IL0.8V

■ Power down protection is provided on all inputs and

outputs

■ Low power dissipation:

I_CC

2 A (max) at T_A25 C

■ Pin and function compatible with 74HCT74

Protection circuits ensure that 0V to 7V can be applied to

the input pins without regard to the supply voltage and to

the output pins with V_CC

0V. These circuits prevent

device destruction due to mismatched supply and input/

output voltages. This device can be used to interface 3V to

5V systems and two supply systems such as battery

backup.
