74HC02; 74HCT02

Quad 2-input NOR gate

Rev. 9 -- 15 February 2024

Product data sheet

1. General description

The 74HC02; 74HCT02 is a quad 2-input NOR 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

? Wide supply voltage range from 2.0 V to 6.0 V ? CMOS low power dissipation ? High noise immunity ? Latch-up performance exceeds 100 mA per JESD 78 Class II Level B ? Input levels:

? For 74HC02: CMOS level ? For 74HCT02: TTL level ? Complies with JEDEC standards: ? JESD8C (2.7 V to 3.6 V) ? JESD7A (2.0 V to 6.0 V) ? ESD protection: ? HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V ? CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V ? Multiple package options ? Specified from -40 ?C to +85 ?C and from -40 ?C to +125 ?C
