The 3V to 5.5V supply range means this part works on a 3.3V rail without a separate 5V supply, simplifying the power tree on mixed-voltage boards. At 3.3V the charge-pump still generates the RS-232 bus voltages, so it is a drop-in for modern low-voltage designs. Receiver hysteresis is specified at 300 mV, which provides noise immunity on the incoming RS-232 lines without external schmitt-trigger buffers. That matters when the cable runs through a noisy electrical cabinet. The base product number is MAX3232, which covers a family of pin-compatible options if you need a different package or temperature grade down the line.","metaTitle":"MAX3232IDBG4 RS-232 Transceiver, 250 kbps, 3V-5.5V, 16-SSOP","metaDescription":"Texas Instruments MAX3232IDBG4 RS-232 transceiver, full duplex, 2/2 driver/receiver, 250 kbps, 3V to 5.5V supply, -40°C to 85°C, 16-SSOP.
