RS-232 transceiver in a DIP — field-swappable, socket-friendly
The MAX202EPE+ is an RS-232 transceiver from Analog Devices, full duplex, with two drivers and two receivers on a single 16-pin DIP package. It runs on a single 4.5V to 5.5V supply and handles data rates up to 120Kbps. The 500 mV receiver hysteresis cleans up noisy lines — typical for RS-232 levels over longer cable runs. The through-hole 16-PDIP package (0.300" body width) is socket-compatible and field-replaceable — no hot-air station needed, just a DIP extractor and a steady hand.

What the supply range and data rate mean on the bench
The 120Kbps data rate is the ceiling; actual throughput depends on cable capacitance and the driver slew rate, but it comfortably handles legacy RS-232 links up to 15 meters at 9600 baud. Full duplex operation with separate driver and receiver pairs means you can send and receive simultaneously on the same connector — no half-duplex handshaking required in firmware.
