74HC21 gate equivalent, dual 4-input and gate.
* 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 I.
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.
