The hysteresis means the receiver won't chatter on a floating or weakly driven line, which saves a software debounce timer in the UART ISR. The MAX3232 family is a staple RS-232 interface — it has been around long enough that the pinout and function are second-source friendly, but TI is still manufacturing it.","metaTitle":"MAX3232IDWRG4 RS-232 Transceiver, 250kbps, 16-SOIC","metaDescription":"TI MAX3232IDWRG4 RS-232 transceiver, 2/2 drivers/receivers, 250kbps data rate, 3V-5.5V supply, -40°C to 85°C, 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":"Tape & Reel (TR)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232IDWRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX3232IDWRG4 and MAX3232IDR?","answer":"The MAX3232IDWRG4 uses the wide-body 16-SOIC package (7.50 mm width), while the MAX3232IDR uses the narrow-body 16-SOIC (3.91 mm width).
