RS-232 link for industrial serial ports
The MAX3226EEUE+ is a single RS-232 transceiver from Analog Devices, handling one driver and one receiver in a full-duplex configuration. It sits on a 16-TSSOP footprint and draws from a 3V to 5.5V supply rail — common in mixed-voltage industrial control boards where the serial port needs to talk to legacy PLCs or programming terminals.
Data rate and signal integrity
Rated for 250kbps, this transceiver supports the standard RS-232 baud rates used in industrial serial links — 115.2kbps and below run with margin. The 500 mV receiver hysteresis cleans up noisy lines from long cable runs in factory-floor environments, reducing the chance of false edge triggers on the UART.
Lifecycle and compliance
Marked as Active by Analog Devices, with ROHS3 compliance — no near-term EOL risk for new designs.
