MC14069UB - CD4069 HEX INVERTER
MC14069UB – CD4069 is a hex inverter IC. Coming to the working system, it reverses the input signal in its digital electronic circuits.
For example, when the input is in logic 1, the output is logic 0. Otherwise, when
input logic is 0, output logic becomes 1.
CD4069, which has 14 pins, has 6 (hex) inverters. All inverters have separate input and output port and each inverter can be controlled individually. It works with 3-18V voltage range and you can get 10mA current.
