The CD74HCT14PWRG4 is a four-input Negative-Edge-Triggered and Schmitt-Triggered (N/E/T/S) Buffer/Inverter. It operates from a single 2.3V to 6V supply and is capable of driving an output voltage up to 35V. This buffer/inverter will draw no more than 1.2 µA at 3V and it is specified from -55°C to 125°C. The CD74HCT14PWRG4 contains 4 Schmitt-Triggered high-performance Buffer/Inverters capable of driving loads up to 33mA, with the outputs rated for up to 35V. It provides true (non-inverted) buffered outputs via the OE* active-low pin.

The CD74HCT14PWRG4 is typically used in applications such as level translators for bidirectional I/O ports, asynchronous memory timing, clock multipliers, race way decoders, multivibrators, shift registers and data buffers, fan-out drivers, logic algebraic operations, and general purpose logic cells. It is also widely used in motor control, battery charging and power supply circuits.

The working principle of the CD74HCT14PWRG4 is quite straightforward. The first three inputs (A, B, and C) are fed into a set of inverting and non-inverting data input buffers, which are configured as a single-ended buffer/inverter pair. The fourth input (D) is fed into another buffer/inverter pair, but with both inputs connected together. When the output enable (OE*) pin is high, the output will be the inverse of the chosen input (A, B, or C). When the output enable pin is low, the output will be the inverse of the fourth input (D).

The CD74HCT14PWRG4 also incorporates Schmitt-Trigger characteristics, making it ideal for noisy environments, or for applications where long delays are required. The Schmitt-Trigger will filter out noise, and the resulting output will not switch until the input has crossed the Schmitt-Trigger threshold. This filter also helps reduce false triggering due to slow or delayed input transitions.

Overall the CD74HCT14PWRG4 is a very versatile chip which can be used for a multitude of applications. It is extremely reliable, and its wide operating range means that it can be used in a range of different power supply systems. Its Schmitt-Trigger characteristics also make it perfect for applications requiring long delays, or where noise levels might be a problem. Its low power consumption and wide temperature range also make it ideal for applications such as medical devices.
