The NC7SZ38FHX is a single 2-input Schmitt trigger inverter gate that is commonly used as a logic gate in communication and computing circuits. The NC7SZ38FHX is a low-power, low-voltage, very fast-switching CMOS Schmitt trigger inverter. It has two inputs and one output.

The NC7SZ38FHX is well-suited for interfacing 5V logic levels to CMOS logic levels because it contains an internal hysteresis level at its input. By utilizing the hysteresis level, the NC7SZ38FHX can prevent oscillations when the input signal has slow rise and fall times. This is advantageous for many applications because the potential for noise problem is reduced due to the hysteresis limit. Furthermore, the use of the CMOS Schmitt trigger ensures excellent dynamic properties.

The application field of NC7SZ38FHX includes electric equipment and circuits such as computers, mobiles, medical equipment, measuring instruments, air conditioners and home appliances. It is mainly used as a circuit element to interface between 5V and CMOS logic levels, as well as used in power switches, logic switches, short circuit detection, etc. The NC7SZ38FHX can also be used as an input port protecting circuit in a microprocessor. It is typically used to decode various address and data buses.

The working principle of the NC7SZ38FHX is based on the CMOS Schmitt trigger, which provides hysteresis to the circuits. Hysteresis is the ability of a circuit to remember the last state of the input without the need for a reference voltage or other external information. The point at which the Schmitt output changes logic level is determined by the threshold voltage of the device. When the input voltage crosses the threshold voltage, the output will toggle, allowing a consistent decision to be made regardless of changes in the input.

The NC7SZ38FHX features an input voltage range of 1.65V up to 5.5V and an output voltage range of 0.2V to VDD. The quiescent current is typically 1.2uA and the propagation delay time is typically 11ns (on a 4.5V supply). The NC7SZ38FHX offers excellent switching characteristics, low power consumption, low noise, and a wide operating temperature range (−40°C to +125°C).

To ensure optimal performance for the NC7SZ38FHX, it is important to consider the component’s package, input signals, power supply, temperature range, and load conditions. The component also has to be compensated for glitches and noise pulses. Additionally, considerations should be made for protection against electrostatic and surge discharge.

In summary, the NC7SZ38FHX is a single 2-input Schmitt trigger inverter gate that offers a wide range of application fields in communication and computing circuits. The component is ideal for interfacing 5V logic levels to CMOS logic levels and for power switches, logic switches, and short circuit detection. The NC7SZ38FHX is based on CMOS Schmitt trigger circuitry, which provides hysteresis, and it provides excellent switching characteristics, low power consumption, low noise, and a wide operating temperature range. It is important to consider the component’s package, input signals, power supply, temperature range, and load conditions when using the NC7SZ38FHX.
