ST485ABDR from STMicroelectronics is an active half-duplex transceiver for RS-422, RS-485 serial interfaces. It integrates 1/1 driver/receiver channels, supports data rates up to 50Mbps, and operates from 4.5V ~ 5.5V.
Selection profile: Its half-duplex architecture shares the bus pair between transmit and receive operation, so direction-control timing should be checked in the final design. The verified interface scope is RS-422, RS-485. The 50Mbps data-rate rating, 4.5V ~ 5.5V supply range, and -40°C ~ 85°C operating range distinguish this orderable part in the catalog.
Package and ordering: ST485ABDR is supplied in SOIC-8; the source package designation is 8-SOIC, with Tape & Reel (TR) Cut Tape (CT) Digi-Reel® packaging options listed for this orderable part. Confirm reel, tube, tray, or cut-tape requirements against the full manufacturer ordering code before purchase.
Use the linked datasheet to verify pinout, protection features, timing limits, termination requirements, and application-specific conditions. Availability, lead time, and order quantity require RFQ confirmation.
