74HC08; 74HCT08
Quad 2-input AND gate
Rev. 8 — 10 August 2021
Product data sheet
1. General description
The 74HC08; 74HCT08 is a quad 2-input AND 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 74HC08: CMOS level • For 74HCT08: 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 JESD22-A114F exceeds 2000 V • MM JESD22-A115-A exceeds 200 V • Multiple package options • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
