74HC20集成电路（IC）的门反相器规格书PDF中文资料

1. General description

The 74HC20 is a dual 4-input NAND 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

• Complies with JEDEC standards:

• JESD8C (2.7 V to 3.6 V)

• JESD7A (2.0 V to 6.0 V)

• CMOS input levels

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• Specified from -40 °C to +80 °C and from -40 °C to +125 °C.
