Product details

1 Mbps RS-232 transceiver – active, 20-SSOP

The MAX3225CAP+T is an Analog Devices RS-232 transceiver with full-duplex operation, supporting a 1 Mbps data rate over a 3V to 5.5V supply range.

Supply range and signal integrity

The wide 3V to 5.5V supply range lets the transceiver operate from common 3.3V or 5V rails without a separate regulator, simplifying power distribution on mixed-voltage boards. Receiver hysteresis of 500 mV provides noise immunity on the RS-232 bus, reducing the risk of false triggering in electrically noisy environments.

Frequently asked questions

What is the difference between MAX3225CAP+T and MAX3223?

The MAX3223 is also an RS-232 transceiver but typically operates at lower data rates (e.g., 250 kbps) and may have different driver/receiver counts or supply voltage ranges. The MAX3225CAP+T offers a 1 Mbps data rate and full-duplex 2/2 configuration, making it better suited for higher-speed serial links.

Is MAX3225CAP+T suitable for 5V-only systems?

Yes, the 3V to 5.5V supply range covers both 3.3V and 5V rails, so it works directly in 5V-only designs without a level shifter.
