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.
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.
