It handles serial data at rates up to 1 Mbps, making it a solid choice for industrial UART links, point-of-sale terminals, and embedded systems that need a reliable serial port without the old 232-level shifters.
Supply voltage flexibility — 3V to 5.5V
Rated for a 3V to 5.5V supply range, this part works cleanly on a 3.3V rail in modern MCU designs or on a legacy 5V bus. No external level translator needed if your logic side matches one of those voltages — the transceiver handles the RS-232 voltage swing internally.
The 500 mV receiver hysteresis helps reject noise on longer cable runs in those environments.
No last-time-buy or end-of-life risk for new designs.
