Overview
The SN74AC244PW is an integrated circuit (IC) produced by Texas Instruments, belonging to the 74AC series of logic ICs. This component is an octal buffer or line driver with 3-state outputs, packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package). It is designed to enhance the performance and density of various digital systems, particularly in applications requiring high-speed data transmission and low power consumption.
The device operates over a supply voltage range of 2V to 6V, making it versatile for different system designs. It features non-inverting buffers, meaning the output signals are the same as the input signals, and includes output enable inputs to control the 3-state outputs. This allows the outputs to be set to a high-impedance state, which is useful in bus-oriented systems.
