ON Semiconductor MC74HCT14A Hex Schmitt-Trigger Inverter

The MC74HCT14A from ON Semiconductor is a high-performance, hex inverter chip with Schmitt-trigger inputs, designed to operate in a wide range of digital applications. This integrated circuit is part of the HCT family, meaning it is compatible with CMOS and TTL logic levels, providing designers with a versatile solution for mixed-technology environments.

The device features six independent inverters with Schmitt-trigger action at all inputs, which allows for noise immunity and the capability to transform slowly changing input signals into sharply defined, jitter-free output signals, enhancing the circuit's overall performance. The enhanced trigger sensitivity makes the MC74HCT14A ideal for applications where input pulses may be slow or noisy, and a stable output is essential.

Constructed with silicon gate CMOS technology, the MC74HCT14A offers the best of both worlds: CMOS low power consumption and TTL compatibility. This combination ensures that the device is suitable for interfacing with microprocessors and other logic families within a system. Additionally, the chip's typical operating voltage ranges from 4.5V to 5.5V, with a guaranteed noise margin of 1V at the standard operating voltage of 5V.

The MC74HCT14A provides additional features such as:

• Output drive capability of 10 LSTTL loads, which translates to a high fan-out capacity.
• Low power consumption characteristic of CMOS devices, with only 20 µA of maximum I<sub>CC static.
• High noise immunity, which is inherent to CMOS technology.
• Functional down to 2V, providing a wide margin for various applications and power supply variations.

This device is available in multiple package options, including the standard DIP, SOIC, and TSSOP, making it suitable for both through-hole and surface-mount technology (SMT) applications. Whether you are designing consumer electronics, automotive systems, or industrial controls, the ON Semiconductor MC74HCT14A offers a reliable and flexible solution for your digital logic needs.
