The 120 kbps ceiling is the classic MAX232 speed — fine for legacy RS-232 at 9600 or 115200 baud, but not for the 1 Mbps capable MAX232A or MAX3232 variants. If your UART is set to 230400 baud or higher, this part will miss bits. For standard industrial protocols (Modbus RTU at 19200, terminal links at 115200), the margin is comfortable. No trick to getting the full rate: the charge-pump capacitors per the datasheet values, and the load capacitance stays under 2500 pF per the RS-232 standard. ## Active lifecycle — no LTB panic needed No last-time-buy notice, no end-of-life flag. If you are stocking spares for legacy boards, the active status means the factory channel is still open — no need to broker-surf yet. ## Field-swap reality: orientation and handling No exposed pad, no thermal-via requirement — just the usual decoupling caps (0.1 µF and 1 µF per the charge-pump layout). If you are swapping this on site without a reflow oven, a hot-air station with fine nozzle and some flux paste will get it done; the body is 3.90 mm wide, so tweezers work.","metaTitle":"MAX232DG4 RS-232 Transceiver, 120 kbps, 2/2 Drivers, 16-SOIC","metaDescription":"Texas Instruments MAX232DG4 RS-232 transceiver, full duplex, 120 kbps data rate, 2 drivers/2 receivers, 4.5V–5.5V supply, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"MAX232","Receiver Hysteresis":"500 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I replace MAX232 with MAX232DG4?","answer":"Yes, the MAX232DG4 is a direct drop-in replacement for the base MAX232 in a 16-SOIC footprint.
