RS232 interface with 4/3 driver/receiver count
The MAX236EWG+ is a full-duplex RS232 transceiver from Analog Devices, integrating four drivers and three receivers in a single 24-SOIC wide package. It handles serial data at 120 kbps over the RS232 protocol, which is the standard for point-to-point asynchronous communication in industrial control, instrumentation, and telecom equipment.
Receiver hysteresis is specified at 500 mV, which provides noise immunity on long cable runs — the 500 mV dead band rejects ground-shift and crosstalk that would otherwise cause bit errors on a 120 kbps line.
Housed in a 24-SOIC (0.295", 7.50 mm width) body with a surface-mount footprint. The wide-body SOIC offers better thermal dissipation than the narrow version and is a common footprint in industrial RS232 interface designs. The supplier device package is 24-SOIC, matching the standard land pattern for this width.
Active production and compliance
The part is ROHS3 compliant, which satisfies the EU RoHS exemption structure for lead-free soldering processes.
