This is the wide-body SOIC variant (7.50 mm width) on tape-and-reel, suited for automated assembly lines. At 120 kbps, this part is a good fit for legacy RS-232 links running at 115.2 kbps or slower — think industrial PLCs, point-of-sale terminals, and serial console ports. If your design targets 1 Mbps or higher (common on newer UARTs), the MAX232 family tops out here; you would need a faster transceiver like the MAX3232 or a dedicated 3.3V part. The 500 mV receiver hysteresis helps reject noise on longer cable runs, which is a practical advantage in factory-floor environments. That means no last-time-buy window to track, no end-of-life scramble. For dual-sourcing, the base product number MAX232 is second-sourced by multiple manufacturers, so pin-compatible alternatives exist if supply tightens. ## Temperature range and industrial fit It is suitable for outdoor telecom cabinets, motor drives, and HVAC controllers where the ambient temperature swings. The 16-SOIC package with 1.27 mm pitch is straightforward to route and hand-solder if needed, though the wide body takes up more board area than the narrow SOIC-16 variant.","metaTitle":"MAX232IDWRE4 RS-232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX232IDWRE4 RS-232 transceiver, 2/2 drivers/receivers, 120 kbps data rate, 4.5V-5.5V supply, -40°C to 85°C, 16-SOIC.
