74AHC32

QUADRUPLE 2-INPUT OR GATES

Description

Pin Assignments

The 74AHC32 provides provides four independent 2-input OR gates

with standard push-pull outputs. The device is designed for operation

with a power supply range of 2.0V to 5.5V. The inputs are tolerant to

5.5V allowing this device to be used in a mixed voltage environment.

The gates perform the Boolean function:

Y = A +B or Y = A • B

Features

•

Wide Supply Voltage Range from 2.0V to 5.5V

Outputs Sink or Source 8mA at V_CC= 4.5V

CMOS Low Power Consumption

Schmitt Trigger Action at All Inputs

Inputs can be driven by 3.3V or 5.5V allowing for voltage

translation applications.

Applications

•

General Purpose Logic

Wide array of products such as:

•

ESD Protection Exceeds JESD 22

200-V Machine Model (A115-A)

PCs, Networking, Notebooks, Netbooks

Computer Peripherals, Hard Drives, CD/DVD ROM

TV, DVD, DVR, Set Top Box

2000-V Human Body Model (A114-A)

Exceeds 1000-V Charged Device Model (C101C)

•

Latch-Up Exceeds 250mA per JESD 78, Class II

Range of Package Options SO-14 and TSSOP-14

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
