Any units you source now come from independent distributors holding inventory — new-old-stock or surplus from overruns. If you have this on a production BOM, you need to qualify a replacement or secure a lifetime buy through a broker.
The SN65HVD10QPG4 is a half-duplex RS485/RS422 transceiver from TI's SN65HVD10 family, supporting data rates up to 32 Mbps. The receiver hysteresis is 35 mV, which helps reject noise on long cable runs.
The wide temperature range means the part maintains signal integrity and drive capability across thermal extremes, not just at room temperature.
Sourcing reality
Because this part is obsolete, you won't find it on TI's active price list. The available stock sits with independent distributors — we can source it against an RFQ, confirming current availability and pricing at quote time. If you need a production-ready alternative, the next FAQ covers the closest pin-compatible replacement within the same family.
