Logic circuit CD74HCT125E - line driver - 4 channels

Alogiccircuit in the form of aline driver, a three-state buffer.It has4 channels, at the output of which appears a state dependent on the state given to the input pins. Three states can appear on the output of the gate, these are: low state, high state and high impedance state. TheCD74HCT125Eis poweredfrom 4.5V to 5.5V DC. The chip is encapsulated in a DIP14 package with THT through-hole mounting.

The CD74HCT125E logic chip.

The circuit is equipped with four channels, at the output of which appears the corresponding state. Pins nOE and nA are input pins, to which a low or high state can be given, while pins nY are output pins, on which a low, high or high resistance state can appear.

H = high state

L = low state

X = any state (low / high)

Z = high impedance state, OFF state
