Product details

RS-232 transceiver with 1 Mbps throughput and wide supply range

The TRSF3223EIPWR: Its 1 Mbps data rate handles legacy serial links and industrial UART interfaces without stretching the bit-time budget. Supply voltage spans 3V to 5.5V, so the part sits on a 3.3V or 5V rail without a separate regulator — one less BOM line to qualify.

Industrial temperature grade and receiver hysteresis

Receiver hysteresis is 500 mV.

The reel option suits automated pick-and-place; the cut tape works for prototype or low-volume builds.
