The Texas Instruments SN74ACT240PWLE is a 4-bit bus driver from the ACT series, designed to buffer and drive capacitive or heavily loaded digital buses in 5 V logic systems. The part is listed with an active product status, so it remains a current-production choice for new builds and repair stock alike.
RoHS status — design-in constraint
This variant is RoHS non-compliant, meaning the device and its finish contain lead or other restricted substances above the exemption thresholds. If your assembly line or end-market requires RoHS conformance, this part cannot be used without an exemption waiver. The non-compliant status is a hard gate for many BOMs — verify your environmental compliance requirements before committing the line.
