At 250 kbps, this transceiver handles standard RS-232 asynchronous data at rates typical for legacy serial ports (115200 baud and below run comfortably). The full-duplex capability means simultaneous transmit and receive on separate pairs, matching the usual TxD/RxD wiring in DB9 connectors. If your application requires higher throughput — say 1 Mbps for industrial protocols — this part is not the right fit; look at the MAX3222 or MAX3243 family for faster slew rates. This simplifies BOM integration in mixed-voltage systems — a 3.3 V microcontroller can drive the transceiver directly, and the RS-232 output swing still meets the ±5 V minimum per the EIA-232 standard. The 300 mV receiver hysteresis provides noise margin on the receive side, which is useful when the cable runs through electrically noisy environments like an office floor.","metaTitle":"MAX3232CDBG4 RS-232 Transceiver, 250 kbps, 16-SSOP","metaDescription":"Texas Instruments MAX3232CDBG4 RS-232 transceiver, full duplex, 250 kbps data rate, 3 V to 5.5 V supply, 16-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"16-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232CDBG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX3232CDBG4?","answer":"The closest pin-compatible alternative within the same family is the MAX3232CDBR, which shares the same 16-SSOP footprint and 2/2 driver/receiver count but differs in packaging (tape-and-reel vs tube).
