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.
Package and temperature grade
Commercial temperature range (0°C to 70°C) limits this part to indoor, climate-controlled environments; for extended-temperature applications, consider the industrial-grade variant in the same family.
