Product details

What this RS-232 transceiver is and where it fits

The Maxim Integrated MAX3238ECAI+ is a full-duplex RS-232 transceiver in a 28-pin SSOP package. It integrates five line drivers and three line receivers, a ratio that suits equipment with more transmit than receive channels — think industrial terminals, point-of-sale gear, or multi-port serial adapters where one UART talks to several peripherals. Operates from a 3V to 5.5V supply rail. Data rate is 250 kbps; receiver hysteresis is 600 mV. Temperature grade is commercial (0°C to 70°C), which covers most indoor and office-environment equipment. Not rated for industrial or automotive extended-temperature zones.

Lifecycle and sourcing posture

The MAX3238ECAI+ carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

Does MAX3238ECAI+ work with a 3.3V supply?

Yes. The supply voltage range is 3V to 5.5V, so it operates directly on a 3.3V rail. The internal charge pump generates the RS-232 output levels from that supply.

What is the difference between MAX3238ECAI+ and MAX3232E?

The MAX3238ECAI+ provides 5 drivers and 3 receivers in a 28-SSOP package, versus the MAX3232E which has 2 drivers and 2 receivers in a smaller 16-pin package. The MAX3238 is the part to pick when your design needs more transmit channels than receive — common in multi-drop or terminal-server applications. Both operate from a 3V to 5.5V supply and run at 250 kbps.
