It integrates three drivers and five receivers, supporting a 250kbps data rate across a 3V to 5.5V supply range. ## 28-SSOP package and board-fit Housed in a 28-SSOP (0.209\", 5.30mm width) surface-mount package — the 0.65mm pitch typical of SSOP-28 demands a 2-layer board with adequate trace breakout under the body. The supplier device package is 28-SSOP, so the land pattern is consistent across TI's SSOP-28 RS232 parts. ## Driver/receiver count and receiver hysteresis With three drivers and five receivers, the MAX3243CDBR handles a typical DB9 RS232 port (TxD, RxD, RTS, CTS, DSR, DCD, RI, DTR) plus a spare receiver channel. The 300 mV receiver hysteresis provides noise immunity on long cable runs — the threshold band rejects line noise below that level without external filtering.","metaTitle":"Texas Instruments MAX3243CDBR RS232 Transceiver, 250kbps","metaDescription":"MAX3243CDBR from Texas Instruments — RS232 full-duplex transceiver, 3/5 driver/receiver, 250kbps data rate, 28-SSOP package.
