RS232 transceiver with full-duplex 3/3 channel count
The MAX1406CWE+ is a full-duplex RS232 transceiver from Analog Devices, integrating three drivers and three receivers in a single 16-SOIC package. It handles data rates up to 230 kbps, making it suitable for point-to-point serial links in industrial control, instrumentation, and telecom equipment where a single supply rail between 4.5 V and 5.5 V is available.
Supply range, receiver hysteresis, and temperature grade
The receiver hysteresis is specified at 650 mV, which provides noise immunity on long cable runs where ground potential differences can reach several hundred millivolts. The commercial temperature range (0°C to 70°C) covers most indoor equipment; for extended ambient environments, a wider-grade variant would be required.
16-SOIC package and board integration
The supplier device package is 16-SOIC, and the part ships in tube packaging.
