74AC08 Datasheet Quad 2-input And Gate

Manufacturer: STMicroelectronics

Overview: 74AC08 QUAD 2-INPUT AND GATE s s s s s wiring C2MOS technology. It is ideal for low power applications mantaining high speed s operation similar to equivalent Bipolar Schottky TTL. s The internal circuit is composed of 2 stages including buffer output, which enables high noise s immunity and stable output.

General Description

protection circuits against static discharge, giving The AC08 is an advanced high-speed CMOS www.DataSheet4U.com QUAD 2-INPUT AND GATE fabricated with them 2KV ESD immunity and transient excess sub-micron silicon gate and double-layer metal voltage.
