At 3.3V nominal, the AM26LV31CNSR interfaces directly with 3.3V UARTs, FPGAs, and MCUs without level shifters. If your system still runs a 5V logic bus, the input thresholds are not 5V-tolerant — you will need external translation or a different driver variant. The 4/0 driver/receiver count means you pair this with a separate RS422/RS485 receiver (like the AM26LV32 or SN75175) for a full transceiver pair. For prototype or low-volume builds, Cut Tape (CT) options are also available. This is a standard catalog part with broad distribution coverage. For BOM planning, the base product number AM26LV31 covers multiple package and temperature variants, so the CNSR (commercial temp, SOIC, Tape & Reel) is the most widely stocked option.","metaTitle":"AM26LV31CNSR Texas Instruments RS422/RS485 Driver, 3V-3.6V","metaDescription":"Texas Instruments AM26LV31CNSR is a quad RS422/RS485 line driver in 16-SOIC, 3V-3.6V supply, 0°C-70°C.

It provides the differential drive for RS485 multi-drop buses, but note it is a driver-only device — you will need a separate RS485 receiver (such as the AM26LV32) for the receive path."},{"question":"Is AM26LV31CNSR compatible with 5V logic?","answer":"Interfacing with 5V logic requires external level translation or a different driver rated for 5V supply."},{"question":"Is AM26LV31CNSR a direct replacement for AM26LV31CNS?","answer":"The AM26LV31CNS and AM26LV31CNSR share the same base product number and electrical specifications. The difference is packaging: CNS is typically Tube, while CNSR is Tape & Reel.
