M54HC20 DUAL 4-INPUT NAND GATE

The M54/74HC20 is a high speed CMOS DUAL 4INPUT NAND GATE fabricated in silicon gate 2 C MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The internal circuit is composed of 3 stages including buffered output, which gives high noise immun.
