Product details

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.

Active production — tape-and-reel supply

Confirm current pricing and lead time via RFQ — the spot market sees consistent availability for this series.
