Texas Instruments 20-SOIC SN74HCT244DW

The part number SN74HCT244DW refers to a Quadruple Bus Transceiver IC from Texas Instruments. It's part of the SN74HCT series, which are high-speed CMOS devices with TTL-compatible inputs and outputs. This specific model is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package and is designed for bidirectional data transmission between two buses, allowing it to function as level translators or as a bus buffer. The 'DW' suffix typically indicates tape and reel packaging for surface mount assembly in high volume production environments.
