General Description

The VHCT04A is an advanced high speed CMOS Inverter fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output.

Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC = 0V. These circuits prevent device destruction due to mismatched supply and input/ output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup.

Features

■ Power down protection is provided on all inputs and outputs

■ Low noise: VOLP = 1.0V (Max.)

■ Low power dissipation: ICC = 2µA (Max.) @ TA = 25°C

■ Pin and function compatible with 74HCT04

74VHCT04A属于集成电路（IC） > 门和反相器。安森美半导体公司制造生产的74VHCT04A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。
