Product details

RS232 line driver/receiver for 5V serial links

The MAX221CUE+T is a single RS232 transceiver from Analog Devices, handling one driver and one receiver in full-duplex mode. It converts 5V logic-level signals to RS232 voltage levels and back, with a data rate of 250 kbps. The part comes in a 16-TSSOP package and operates over the commercial temperature range of 0°C to 70°C. Typical applications include point-of-sale terminals, serial port adapters, and industrial control panels where a single RS232 port is needed on a 5V supply rail.

250 kbps — what it means for the serial link

The 250 kbps data rate covers standard RS232 baud rates with margin. The 500 mV receiver hysteresis cleans up noisy lines, reducing bit errors on long cable runs without external filtering.

Lifecycle and sourcing

Active product status per the manufacturer — no end-of-life notice, no last-time-buy pressure. ROHS3 compliant.

Frequently asked questions

Does MAX221CUE+T support data rates up to 250 kbps and is it compatible with 5V RS232 standards?

Yes, it supports a data rate of 250 kbps and is fully compatible with 5V RS232 voltage levels.

What are direct alternatives or equivalent parts to MAX221CUE+T?

Pin-compatible alternatives include the MAX3221 family from the same manufacturer, which offers similar functionality with a wider supply range or higher data rates. Verify the pinout and charge-pump configuration before substituting.
