74HC21
description
The 74HC21 is a dual 4-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 to 6.0 V
- CMOS low power dissipation
- High noise immunity
- Latch-up performance exceeds 100 m A per JESD 78 Class II Level B
- CMOS input levels
- plies with JEDEC standards:
- JESD8C (2.7 V to 3.6 V)
- JESD7A (2.0 V to 6.0 V)
- ESD protection:
- HBM JESD22-A114E exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- Specified from -40 °C to +85 °C and from -40 °C to +125 °C.
