High Speed CMOS Logic – 74HC20

Rev 1.0

7/5/2019

Features:

 

Dual 4-Input NAND Gate IC in bare die form

 

 

 

 

 

 

 

The 74HC20 Dual 4-Input NAND Gate is made using a

2.5µm 5V CMOS process & combines the high speed

of LSTTL with CMOS low power consumption. The

device performs Boolean functions Y = (A • B • C • D)

or Y = A + B + C + D in positive logic. Inputs accept

standard CMOS outputs or LSTTL outputs using pull-

up resistors. Internal circuitry comprises 3 stages &

includes buffered output for high noise immunity &

stability. Inputs are equipped with protection circuits

against static discharge & transient excess voltage.

Description
