RS232 link — one channel, full duplex
The MAX3221CUE+T: It handles a 235 Kbps data rate — enough for legacy serial ports, debug UARTs, and low-speed peripheral links where the cable run stays under a few meters.
Supply tolerance and temp range
The receiver hysteresis is 300 mV, which filters noise on long cable runs. Not for under-hood or outdoor ambient without a heated enclosure.
