At 400kbps the ST202CDR handles standard UART speeds with margin. The 500 mV hysteresis on the receiver inputs helps reject ground-shift noise.
Surface-mount package with 0.154" body width and 3.90 mm height. The supplier device package is 16-SO.
The ST202CDR is a full-duplex RS232 transceiver with 2/2 drivers/receivers at 400kbps. A common cross-shop candidate is the MAX232 family, which shares the same 16-SOIC footprint and 5V supply but typically runs at 120kbps — the ST202CDR offers higher data rate and 500 mV hysteresis for better noise margin. Verify pinout and capacitor values against your layout before substituting.
The ST202CDR is a Transceiver with Full duplex operation, meaning it can transmit and receive simultaneously on separate pairs.
