If your design needs bidirectional RS485 communication, you must add an external receiver IC. For pure transmit-only applications — broadcasting data from a controller to multiple remote nodes — the 4/0 count is exactly what you want, saving the cost and board area of unused receiver channels. ## Lifecycle and supply posture The MAX3043CUE+ carries an Active lifecycle status and is ROHS3 compliant. No official second-source alternate is listed on this record, so dual-sourcing would require a pin-compatible evaluation against a different vendor's quad RS485 driver.","metaTitle":"MAX3043CUE+ RS422 RS485 Driver, 250kbps, 16-TSSOP","metaDescription":"MAX3043CUE+ is a Maxim RS422/RS485 driver with 4 drivers, 0 receivers, 250kbps data rate, 4.75-5.25V supply, 0-70°C, 16-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Driver","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-TSSOP","Number of Drivers/Receivers":"4/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.43","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.43000","currency":"USD"},{"qty":10,"price":"$6.71000","currency":"USD"},{"qty":25,"price":"$6.39800","currency":"USD"},{"qty":100,"price":"$5.55520","currency":"USD"},{"qty":250,"price":"$5.30552","currency":"USD"},{"qty":500,"price":"$4.83740","currency":"USD"},{"qty":1000,"price":"$4.21322","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX3040-MAX3045.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MAX3043CUE+ and MAX3042CUE+?","answer":"The MAX3043CUE+ is a quad driver (4 drivers, 0 receivers), while the MAX3042CUE+ is a dual driver (2 drivers, 0 receivers).
