CD4093 Logic Gate and inverter
This content will be shared across all product pages.
The CD4093 is a CMOS logic IC that integrates four independent Schmitt trigger circuits within a single package. Each Schmitt trigger circuit in the CD4093 performs the function of a 2-input NAND gate with Schmitt trigger action. This means it converts noisy digital input signals into clean digital outputs with hysteresis, improving noise immunity and signal integrity. The CD4093 operates with low power consumption, high noise immunity, and can function over a wide range of supply voltages.
