74HCT08
QUADRUPLE 2-INPUT AND GATES
Description
The 74HCT08 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 4.5V to 5.5V.
The gates perform the Boolean function:
Pin Assignments
Y = A • B or Y = A + B
Features
• Wide Supply Voltage Range from 4.5V to 5.5V
• Pin Compatible with Low Power Schottky (LSTTL)
• Inputs Are TTL Voltage Level Compatible
• Sinks or sources 4mA at VCC = 4.5V
• CMOS low power consumption
• Schmitt Trigger Action at All Inputs
• 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)
• 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)
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.

Notes:
4. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should
be within recommend values.
5. Input Voltage cannot exceed VCC to the extent the maximum clamp current is exceeded.
