Functional Description

• Quad 2-Input OR Gate

General

The 74HC32D is a high speed CMOS 2-INPUT OR GATE fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

The internal circuit is composed of 2 stages including buffer output, which provide high noise immunity and

stable output.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features

(1) High speed: tpd = 6 ns (typ.) at VCC = 5 V

(2) Low power dissipation: ICC = 1.0 μA (max) at Ta = 25 

(3) Balanced propagation delays: tPLH ≈ tPHL

(4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
