What is 74244?
This is Octal 3-STATE Buffer/Line Driver/Line Receiver. A semiconductor buffer driver is an electronic circuit used to isolate and amplify signals between two different electronic systems or components. It is typically used in applications where it is necessary to transfer a signal from a source with a high output impedance to a load with a low input impedance, or vice versa. The buffer drive provides a low-impedance output and a high-impedance input, which helps to prevent signal loss and distortion. |
