It delivers 100 Mbps data rate across four independent driver channels, operates from either a 3V or 5V supply, and is rated for the -40°C to 85°C industrial temperature range. This part is suited for high-speed differential data transmission in factory automation, outdoor telecom, and instrumentation backplanes where signal integrity over twisted-pair cabling matters. ## 100 Mbps — what it means for the bus At 100 Mbps, this driver supports high-throughput links such as Profibus or custom point-to-point serial backplanes. The 4/0 driver/receiver count means you get four transmit channels with no onboard receivers — plan for external RS485 receivers if full duplex is needed. The 3V/5V supply flexibility lets it interface directly with 3.3V FPGAs or 5V legacy logic without level translation. ## Package and mounting Housed in a 16-SOIC (0.154\" body width, 3.90 mm) — a common footprint that fits standard pick-and-place and reflow profiles. The tube shipment suits low-to-medium volume builds; for reel quantities, confirm the tape-and-reel suffix variant if your line runs high volume. ## Lifecycle and compliance Listed as Active with ROHS3 compliance. The LTC1689IS#PBF is the lead-free, RoHS-compliant ordering code; verify your internal BOM matches this suffix for Pb-free assembly.","metaTitle":"LTC1689IS#PBF RS422/RS485 Driver, 100Mbps, 16-SOIC","metaDescription":"LTC1689IS#PBF quad RS422/RS485 driver from Analog Devices. 100Mbps data rate, 3V/5V supply, -40°C to 85°C, 16-SOIC.
