1. General description

The 74AHC00; 74AHCT00 are quad 2-input NAND gates. Inputs are overvoltage tolerant. This

feature allows the use of these devices as translators in mixed voltage environments.

2. Features

• Wide supply voltage range from 2.0 V to 5.5 V

• Input levels:

• For 74AHC00: CMOS level

• For 74AHCT00: TTL level

• Balanced propagation delays

• All inputs have Schmitt-trigger actions

• Overvoltage tolerant inputs to 5.5 V

• High noise immunity

• CMOS low power dissipation

• ESD protection:

• HBM EIA/JESD22-A114E exceeds 2000 V

• MM EIA/JESD22-A115-A exceeds 200 V

• CDM EIA/JESD22-C101C exceeds 1000 V

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

• Multiple package options

• Specified from -40 °C to +85 °C and from -40 °C to +125 °C

74AHC00属于集成电路（IC） > 门和反相器。安世半导体(中国)有限公司制造生产的74AHC00门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
