CD74HC08ME4

高速 CMOS 逻辑四路 2 输入与门 14-SOIC -55 to 125

Description

The CD54HC08, CD54HCT08, CD74HC08, and CD74HCT08 logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The 74HCT logic family is functionally pin compatible with the standard 74LS logic family.
