NXP Semiconductors. 

74HC20; 74HCT20

Dual 4-input NAND gate

Rev. 3 — 3 September 2012

Product data sheet

1. General description

The 74HC20; 74HCT20 is a dual 4-input NAND gate. Inputs include clamp diodes. This

enables the use of current limiting resistors to interface inputs to voltages in excess of

VCC.

2. Features and benefits

 Complies with JEDEC standard JESD7A

 Low-power dissipation

 Input levels:

 For 74HC20: CMOS level

 For 74HCT20: TTL level

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V

 Multiple package options

 Specified from 40 C to +80 C and from 40 C to +125 C.
