1. General description

The HEF4002B is a dual 4-input NOR gate. The outputs are fully buffered for highest

noise immunity and pattern insensitivity to output impedance variations.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS

(usually ground). Unused inputs must be connected to VDD, VSS, or another input.

2. Features and benefits

 Fully static operation

 5 V, 10 V, and 15 V parametric ratings

 Standardized symmetrical output characteristics

 Inputs and outputs are protected against electrostatic effects

 Specified from 40 C to +85 C

 Complies with JEDEC standard JESD 13-B

HEF4002B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HEF4002B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。
