Quad 2-Input OR Gate

The TC74HCT32A 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.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

The internal circuit is composed of 4 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

• High speed: tpd = 12 ns (typ.) at VCC = 5 V

• Low power dissipation: ICC = 1 μA (max) at Ta = 25°C

• Compatible with TTL outputs: VIH = 2 V (min)

VIL = 0.8 V (max)

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 10 LSTTL loads

• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)

• Balanced propagation delays: tpLH ∼− tpHL

• Pin and function compatible with 74LS32

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.
