Overview
The SN74ACT244NSRG4 is an octal buffer and line driver IC manufactured by Texas Instruments. It is designed to enhance the performance and integration density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device operates with high speed and minimal power consumption, making it ideal for driving capacitive loads or interfacing high-performance logic circuits. The SN74ACT244NSRG4 is structured as two 4-bit buffers and drivers, each with its independent output-enable (OE) input. When the OE input is low, the device transmits non-inverted data from the A inputs to the Y outputs. Conversely, when the OE input is high, the outputs transition to a high-impedance state.
