Receiver hysteresis is specified at 300 mV, which gives clean edge detection on noisy RS-232 lines without external schmitt triggers.","metaTitle":"MAX3222CPW RS-232 Transceiver, 250 kbps, 20-TSSOP","metaDescription":"MAX3222CPW is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, in a 20-TSSOP package.","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":"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":"$2.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222CPW/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MAX3222CPW?","answer":"The MAX3222CPW is obsolete from the factory, but we source it through independent distribution.
