CD74HCT86ME4

高速CMOS逻辑四路2输入异或门 High-Speed CMOS Logic Quad 2-Input EXCLUSIVE-OR Gate

Description

The ’HC86 and ’HCT86 contain four independent EXCLUSIVE OR gates in one package. They provide the system designer with a means for implementation of the EXCLUSIVE OR function. 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 HCT logic family is functionally pin compatible with the standard LS logic family.
