概要
Description
The MC74VHC14DR2G is a high-speed CMOS Schmitt trigger inverter from ON Semiconductor's VHC family. It provides a higher speed operation with lower power dissipation than standard logic families. This device features six independent Schmitt trigger inverters, each having a single input and output. It is designed to accept standard TTL input levels and translate them into CMOS output levels, making it ideal for interfacing between different logic families.
One of the key features of the MC74VHC14DR2G is its ability to handle slow or noisy input signals by incorporating a Schmitt trigger input, which provides hysteresis. This characteristic improves noise immunity and provides more stable and reliable operation in noisy environments. The device operates over a wide voltage range, from 2.0V to 5.5V, and is typically used in applications such as signal conditioning, waveform shaping, and creating reliable logic level transitions.
The MC74VHC14DR2G is housed in a small SOP-14 package, making it suitable for compact circuit designs. It is widely used in electronics projects requiring fast and efficient logic operations.

Pinout
The MC74VHC14DR2G is a hex Schmitt-trigger inverter integrated circuit. It typically comes in a 14-pin package, such as a TSSOP-14 or SOIC-14. Each of the six inverters can condition a noisy input signal by providing hysteresis through the Schmitt-trigger design, which helps improve signal integrity by eliminating noise and providing clean digital output transitions.
The pin configuration generally includes:
1. Supply Voltage (Vcc) pin
2. Ground (GND) pin
3. Six pairs of input and output pins, each corresponding to one inverter (e.g., A1/Y1, A2/Y2, ..., A6/Y6).
In a typical pin configuration:
- Pin 1: A1 (Input for first inverter)
- Pin 2: Y1 (Output for first inverter)
- ...
- Pin 13: A6 (Input for sixth inverter)
- Pin 14: Vcc (Supply voltage)
The precise pin configuration should be verified in the manufacturer's datasheet, as variations can exist based on the specific package type.
