It handles data rates up to 400 kbps, which covers standard UART speeds up to 115.2 kbps with margin for higher baud rates on shorter cable runs. Supply voltage spans 3V to 5.5V, so the same BOM position works on a 3.3V microcontroller rail or a legacy 5V UART bus without an external level translator. ## Driver/receiver count and receiver hysteresis With five drivers and three receivers, this transceiver supports three full RS-232 ports (TX/RX plus RTS/CTS handshake) and leaves two spare drivers for auxiliary signals like DTR or DSR. The 300 mV receiver hysteresis filters out noise on long cable runs, reducing false start-bit detection. ## Package and temperature grade for commercial equipment The 28-TSSOP package (4.40 mm width, 0.65 mm pitch) is a common footprint that places cleanly on two-layer boards.","metaTitle":"MAX3238ECPW RS-232 Transceiver 5/3 28-TSSOP – Texas","metaDescription":"MAX3238ECPW RS-232 transceiver, 5 drivers/3 receivers, 400 kbps, 3V–5.5V supply, 28-TSSOP.
