ON Semiconductor MC74HC14DR2G Hex Schmitt-Trigger Inverters

The MC74HC14DR2G is a high-performance, integrated circuit designed by ON Semiconductor, featuring six independent Schmitt-trigger inverters. This product is a part of the high-speed CMOS family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL inverters, while maintaining the CMOS low power dissipation.

With its robust design, the MC74HC14DR2G is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals, making it an ideal choice for applications that require wave shaping or noise elimination. The device is designed to operate from a wide range of power supply voltages, from 2V to 6V, while providing the capability to drive 10 LSTTL loads, offering flexibility and compatibility with a variety of digital systems.

Each inverter in the MC74HC14DR2G features a Schmitt-trigger action at all inputs, which makes the circuit tolerant to slower input rise and fall times. This characteristic is especially important in applications where noise or longer wire lengths can affect signal quality. The hysteresis voltage between the positive-going and negative-going input thresholds (typically 0.9V at VDD = 5V) provides enhanced noise immunity and allows the device to be used as a debouncer for mechanical switches without additional external components.

The MC74HC14DR2G is provided in a compact SOIC-14 package, making it suitable for space-constrained applications. It is also characterized for operation over the full temperature range of -55°C to 125°C, ensuring reliable performance in a wide range of environments and applications, including control systems, signal conditioning, and communication systems.

ON Semiconductor's commitment to quality and environmental sustainability is evident in the MC74HC14DR2G, which is lead-free, halogen-free, and RoHS compliant. This device not only meets the stringent requirements of modern electronic applications but also supports the efforts towards environmentally friendly manufacturing practices.

In summary, the MC74HC14DR2G from ON Semiconductor is a versatile, high-performance solution for digital logic applications requiring Schmitt-trigger inputs, offering robust noise immunity, low power consumption, and reliable operation in a wide range of conditions.
