It delivers a 30 Mbps data rate — enough for high-speed industrial backplanes, motor drive feedback links, and avionics data buses. With four drivers and no receivers, this IC handles the transmit side of a multipoint bus. You will need a separate RS485 receiver per node to complete the transceiver pair. ## Military temperature grade and supply range The commercial-grade SN65LBC174A tops out at 85°C, so the 'MDWREP' suffix buys you 40°C more headroom on the hot end. Supply voltage is 4.75V to 5.25V, a tight 5V rail that demands a clean power supply — expect to decouple with a 0.1 µF ceramic near each VCC pin. ## Active production — sourcing and package The part ships in Tape & Reel (TR) or Cut Tape (CT) options, 20-SOIC wide-body (0.295-inch, 7.50 mm width) — a standard footprint that runs on most pick-and-place lines. ROHS3 compliant. No lead or halogen restrictions beyond the current EU directive. ## Noise margin with 40 mV hysteresis The receiver hysteresis is 40 mV typical, which means the input threshold has a built-in deadband that rejects small noise glitches on long cable runs. On a 1000-meter RS485 stub at 30 Mbps, this hysteresis keeps the output from chattering on common-mode noise from nearby VFDs.","metaTitle":"SN65LBC174AMDWREP RS485/RS422 Driver, 30 Mbps","metaDescription":"Texas Instruments SN65LBC174AMDWREP is a 4/0 differential line driver for RS422/RS485, rated 30 Mbps, -55°C to 125°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Driver","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"30Mbps","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"40 mV","Operating Temperature":"-55°C ~ 125°C","Supplier Device Package":"20-SOIC","Number of Drivers/Receivers":"4/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.47000","currency":"USD"},{"qty":10,"price":"$12.38100","currency":"USD"},{"qty":25,"price":"$11.86800","currency":"USD"},{"qty":100,"price":"$10.45660","currency":"USD"},{"qty":250,"price":"$9.94344","currency":"USD"},{"qty":500,"price":"$9.30192","currency":"USD"},{"qty":1000,"price":"$9.07800","currency":"USD"},{"qty":2000,"price":"$9.07800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3428cf1f1c88b12c593b52826faea2d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SN65LBC174AMDWREP and the standard SN65LBC174A?","answer":"The primary difference is the temperature range.
