The 2/2 driver/receiver count suits applications needing one full-duplex port plus one additional channel, such as a debug console alongside a primary data link. ## Supply voltage and data rate — the practical fit The 500 kbps rating is the maximum; actual throughput depends on cable length and capacitive load. ## Pin-compatible replacement search Because the MAX3222ECPW is obsolete, the most practical fix is finding a pin-compatible RS-232 transceiver in the same 20-TSSOP footprint. Texas Instruments' MAX3222E family includes several variants; the key difference is often the temperature grade (industrial vs commercial) and data rate. The MAX3222ECPW is the commercial-temperature (0°C to 70°C) variant. A direct replacement would need the same 2/2 driver/receiver count, same supply range, and same package. The base part number MAX3222E (without the 'C') is the industrial-temperature version and may be a functional alternate, but verify the pinout matches — TI sometimes changes pin assignments across temperature grades.","metaTitle":"MAX3222ECPW RS-232 Transceiver, 500 kbps","metaDescription":"MAX3222ECPW is a full-duplex RS-232 transceiver with 500 kbps data rate, 2/2 drivers/receivers, 3V-5.5V supply, 20-TSSOP.","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":"500kbps","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3222","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"20-TSSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/445041c92021f26997981b64349fda77.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222ECPW/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of MAX3222ECPW?","answer":"It comes in a 20-TSSOP package (4.40 mm width)."},{"question":"Can MAX3222ECPW replace MAX3222E?","answer":"The MAX3222ECPW is the commercial-temperature variant (0°C to 70°C) of the MAX3222E family.
