If your BOM calls for the industrial range, check the suffix — the 'E' in the middle of the order code here indicates the commercial grade. ## Package and temperature — fits indoor, controlled environments For outdoor or under-hood applications, you would need an industrial-rated sibling.","metaTitle":"MAX3222ECPWG4 RS-232 Transceiver, 500 kbps, 20-TSSOP","metaDescription":"MAX3222ECPWG4 is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 500 kbps data rate, 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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/445041c92021f26997981b64349fda77.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222ECPWG4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MAX3222ECPWG4?","answer":"The MAX3222ECPWG4 is available to order through independent distribution.
