As a transceiver, it combines a driver and receiver in one package, handling bus contention and direction control without external glue logic. This class of device is common in industrial control panels, telecom line cards, and older computing systems where parallel bus architectures still operate. The RoHS non-compliant status is a design-level constraint — if your assembly line is lead-free, you will need to verify exemption allowances or plan for a separate solder profile. For legacy builds that still use SnPb, this is the exact part to specify. ## Bulk packaging — prototype and low-volume fit For a bus transceiver used in prototype bring-up, rework, or small production runs, Bulk is the practical choice — no reel fees, no tape-out minimums. If you are feeding a pick-and-place line at high volume, confirm you have a Tape & Reel variant or a tube feeder available.","metaTitle":"SN74AS2640N Bus Transceiver, Active, Bulk","metaDescription":"TI SN74AS2640N bus transceiver, active lifecycle, Bulk package, RoHS non-compliant.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3","priceTiers":[{"qty":91,"price":"$3.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1e4e0bbc1a0b34f5164cf4ca0d554f43.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74AS2640N/alternatives.json"},"ai":{"faq":[{"question":"Is the SN74AS2640N 5V compatible?","answer":"Yes, the SN74AS2640N is part of the AS logic family, which is designed for 5 V operation.
