Device identity and function
The SN74AS353BDR is a Texas Instruments AS-series 4-line input TTL multiplexer (MUX) in the Interface & Transceivers category. It selects one of four data inputs and routes it to a single output, controlled by two address lines, operating on standard TTL logic levels.
This part is RoHS non-compliant, which is a key consideration for builds requiring lead-free assembly per EU directives. Verify your project's exemption or accept the non-compliant status before committing the BOM line.
Supplied in Bulk packaging, which means the devices are loose in a tube or tray rather than tape-and-reel. This suits prototype runs, low-volume builds, or manual placement but will require a feeder change on high-speed pick-and-place lines.
