高速CMOS逻辑四路2输入与非门 High Speed CMOS Logic Quad 2-Input NAND Gate
Description
The CD54HC00, CD74HC00, CD54HCT00, and CD74HCT00 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.
