74HC21 Overview
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.
74HC21 Key Features
- Wide supply voltage range from 2.0 to 6.0 V
- CMOS low power dissipation
- High noise immunity
- Latch-up performance exceeds 100 mA 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
