HCF4093YM013TR is a quadruple 2-input NAND Schmitt trigger gate integrated circuit (IC). It is designed for use in digital VLSI system circuits, such as microprocessor circuits, and in analog-digital signal conversion systems. It is often used to make logic level conversion from TTL based devices to CMOS based logic devices. It can also be used as a precision clock generator.

The HCF4093YM013TR is composed of four independent 2-input NAND Schmitt triggers. All four inputs have Schmitt trigger action, allowing them to operate with hysteresis from both positive-going and negative-going signals. This ensures a "clean" output pulse, which improves noise immunity, by minimizing oscillations. Schmitt triggers provide superior response to switching noise, and can operate with a wide range of input logic levels.

HCF4093YM013TR can be used in a wide range of applications, including analog-to-digital conversion, pulse generators, oscillators, logic level converters and clock generator circuits. The versatile IC can be used in applications where noise rejection is an important requirement, such as automotive and industrial electronics, instrumentation and communication systems. The IC is also useful for data acquisition, switching, digital signal processing and test and measurement systems.

HCF4093YM013TR has a low power consumption of 1.5 magneta volts maximum (1.5 V typ) and is capable of operating over a wide temperature range from –55°C to +125°C. The IC also has an operating frequency range of up to 100 MHz. HCF4093YM013TR has a high impedance output state at ‘on’ condition, allowing multiple gate outputs to be connected with no cross talk between them.

HCF4093YM013TR’s working principle is based on the fact that a single NAND gate is composed of one inverter and two pass transistors. When the Inputs (A and B) of the gates are LOW, the inverter output is HIGH, turning off both pass transistors. This means that the output of the gate (Y) will be HIGH. Conversely, when the Inputs are HIGH, the output of the gate will be LOW.

However, HCF4093YM013TR is different from the conventional NAND gate because it has three levels of input sensitivity, characterized by the Schmitt trigger hysteresis. This hysteresis between the high and low input thresholds allows the gate to reject noise signals, which are transient signals that may occupy the space between the thresholds. This helps eliminate output oscillations.

In summary, the HCF4093YM013TR is a useful and versatile IC that can be used in a wide variety of applications, including analog-to-digital converters, pulse generators, logic level converters, clock generator circuits and noise control circuits. Its low power consumption and wide operating temperature range make it an ideal choice for applications requiring low power and high reliability.
