The MC74HC14A is identical in pinout to the LS14, LS04 and the HC04. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

The HC14A is useful to “square up” slow input rise and fall times. Due to hysteresis voltage of the Schmitt trigger, the HC14A finds applications in noisy environments.

Features

• Output Drive Capability: 10 LSTTL Loads

• Outputs Directly Interface to CMOS, NMOS and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 A

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance With the JEDEC Standard No. 7.0 A Requirements

• Chip Complexity: 60 FETs or 15 Equivalent Gates

• Pb−Free Packages are Available

MC74HC14ADR2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MC74HC14ADR2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。
