For a production line already qualified on this transceiver, the decision is immediate: secure lifetime-buy inventory or qualify a drop-in replacement before the window shuts. Through independent distribution, we can source remaining stock and quote to order — but the clock is running on fresh TI production. ## Supply voltage and 5V logic compatibility If your UART or controller runs at 5V, you need a level translator or a 5V-tolerant transceiver variant. The receiver inputs are RS-485 bus pins and handle the common-mode range of the differential bus, but the driver enable (DE) and data input (DI) pins see the supply rail. Driving them with 5V logic without a series resistor or level shifter risks latch-up or overstress. Check the absolute maximums in the datasheet before tying directly to a 5V MCU.","metaTitle":"SN65HVD12D RS-485/422 Transceiver, 1 Mbps, 8-SOIC, Last Buy","metaDescription":"TI SN65HVD12D half-duplex RS-485/422 transceiver, 1 Mbps, 3V-3.6V supply, -40°C to 85°C.

A drop-in alternative would be another 3.3V, half-duplex, 1 Mbps RS-485 transceiver in the same footprint, such as the SN65HVD12DR (tape-and-reel variant) or a second-source like the MAX3485.
