RS-232 transceiver with flexible supply range
The 250kbps data rate covers standard serial port communication for industrial control, point-of-sale terminals, and telecom equipment.
At 250 kbps, this transceiver handles typical RS-232 asynchronous data up to about 31 KB/s. That is adequate for terminal interfaces, configuration ports, and low-throughput sensor links, but it will bottleneck a high-speed modem or a firmware-over-UART update running at 1 Mbps. The receiver hysteresis of 300 mV provides noise immunity on longer cable runs, reducing bit errors in electrically noisy environments.
The MAX3232IDB is officially obsolete per the manufacturer's product status.
Housed in a 16-SSOP (0.209", 5.30mm width) surface-mount package, the MAX3232IDB fits tight PCB layouts common in space-constrained designs.
