4093 IC Quad 2-Input NAND Schmitt Trigger
The CD4093BE is a versatile CMOS logic IC that integrates four 2-input NAND gates with Schmitt Trigger inputs. It enhances noise immunity and signal integrity in digital systems by combining the NAND logic function with hysteresis on each input, thanks to the built-in Schmitt Trigger action. This feature allows the IC to clean up noisy or slow-changing input signals, making it ideal for waveform shaping, signal conditioning, and debounce circuits.
This quad NAND gate operates efficiently across a wide supply voltage range of 3V to 15V, making it suitable for both TTL and CMOS environments. Each gate responds with rapid switching while maintaining low power consumption. Its robust construction supports a wide temperature range, making it a reliable solution for industrial, educational, and prototyping applications.
