Texas Instruments 20-SOIC SN74ACT245DW

The SN74ACT245DW is a high-speed CMOS Octal Bus Transceiver from Texas Instruments, designed for low power consumption and improved noise immunity. It functions as a bidirectional buffer with three-state outputs, enabling data transmission between two buses in both directions. This device is housed in a 20-pin SOIC package (Small Outline Integrated Circuit) and conforms to the ACT logic family, providing fast switching times with reduced power dissipation compared to TTL equivalents like the SN74HCT245. The part is typically used for bus expansion or interface level translation in digital systems.
