Working Principles

The SN74ABT244ANSRG4 is a non-inverting buffer/line driver IC. It takes input signals from the A1-A5 and B1-B4 pins and provides corresponding buffered outputs at the Y1-Y5 pins. The output enable (OE) pins control the activation of the outputs. When OE is low, the outputs are enabled and mirror the inputs. When OE is high, the outputs are disabled and remain in a high-impedance state.

The IC operates on a supply voltage range of 4.5V to 5.5V and can drive output currents up to ±24mA. It has a fast propagation delay time of 3.8ns, making it suitable for high-speed applications.
