74AHC08

QUADRUPLE 2-INPUT AND GATES

Description

The 74AHC08 provides provides four independent 2-input AND 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:

BAY •= or BAY +=

Features

• Wide Supply Voltage Range from 2.0V to 5.5 V

• Outputs Sink or Source 8 mA at VCC = 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.

• ESD Protection Exceeds JESD 22

 200-V Machine Model (A115-A)

 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)

Pin Assignments

Applications

• General Purpose Logic

• Wide array of products such as:

 PCs, Networking, Notebooks, Netbooks

 Computer Peripherals, Hard Drives, CD/DVD ROM

 TV, DVD, DVR, Set Top Box

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.
