CD4069 Hex Inverter

Contents hide

The CD4069 consists of six inverter circuits and is manufactured using complementary MOS (CMOS) to achieve wide power supply operating range, low power consumption, high noise immunity, and symmetric controlled rise and fall times. This device is intended for all general purpose inverter applications where the special characteristics of the MM74C901, MM74C907, and CD4049 Hex Inverter/Buffers are not required. In those applications requiring larger noise immunity the MM74C14 or MM74C914 Hex Schmitt Trigger is suggested. All inputs are protected from damage due to static discharge by diode clamps to VDD and VSS

What is a Hex Inverter?

A hex inverter is a simple digital logic circuit that can generate logical inverse any input signal. The output of a hex inverter is always high (1) when the input signal is low (0). Similarly, a hex inverter always yields a low (0) output when the input signal is high (1).
