74VHC32

Quad 2-Input OR Gate

General Description

The VHC32 is an advanced high speed CMOS 2-Input OR

Gate fabricated with silicon gate CMOS technology. It

achieves the high speed operation similar to equivalent Bi-

polar Schottky TTL while maintaining the CMOS low power

dissipation.

The internal circuit is composed of 4 stages including buffer

output, which provide high noise immunity and stable out-

put. An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt-

age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery back up. This circuit

prevents device destruction due to mismatched supply and

input voltages.

Capacitance

Note 1: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average

operating current can be obtained by the equation: ICC (opr.) eCPD *VCC *fIN aICC/4 (per gate).
