onsemi 20-SOIC MC74ACT640DWG

The MC74ACT640DWG is an octal 3-state inverting transceiver IC from the 74ACT series. It facilitates asynchronous bidirectional communication between data buses, with data transmission occurring from bus A to bus B when T/R input is high and vice versa when T/R is low. This device can be disabled using an enable input for effective isolation. Available in a surface mount package, it's suitable for digital logic applications requiring bus interfacing and level translation. The DWG suffix typically indicates a specific manufacturer's package type or ordering code.
