The supply range directly matches 3.3 V ±10% rails common in modern MCU and FPGA systems. No extra level translator is needed when the UART or SPI port of a 3.3 V controller drives the AM26LV31IDR inputs. The 3V lower bound also covers 3.0 V coin-cell or battery-backed domains, though the driver's output differential voltage will be at the lower end of the RS-422 spec at that rail — check the receiver threshold margin if the cable run exceeds a few metres. ## 16-SOIC narrow-body — footprint and rework The 16-SOIC package uses the narrow-body 3.90 mm width. The active status also simplifies multi-year supply commitments — no need to stockpile or budget for a forced redesign.","metaTitle":"TI AM26LV31IDR RS-422/RS-485 Quad Driver, 3V–3.6V","metaDescription":"Texas Instruments AM26LV31IDR quad differential line driver.

The AM26LV31IDR is specified for both RS-422 and RS-485 protocols.
