10 Mbps half-duplex RS-485 transceiver in a 3x3 LFCSP
The ADM4853ACPZ-REEL7 from Analog Devices is a single-channel, half-duplex RS-485/RS-422 transceiver that handles 10 Mbps signaling on a 5V supply rail. The 20 mV of receiver hysteresis cleans up noisy differential lines common in factory-floor runs.
What the 10 Mbps data rate means for your bus
At 10 Mbps, this part supports Profibus DP, DMX512, and other high-speed serial protocols that run over RS-485 physical layers. The half-duplex architecture means you manage direction control via the driver enable pin — typical for multi-drop polled networks. If your application only needs 2.5 Mbps, the ADM4852ACPZ-REEL7 is a lower-speed sibling in the same package and pinout, but the 10 Mbps part gives you headroom for future throughput increases without a board spin.
Package and layout: 8-LFCSP (3x3) with exposed pad
The 8-LFCSP (3x3) measures 3 mm x 3 mm with an exposed thermal pad underneath. The part is surface-mount only, so hand-prototyping requires a hot-air station or reflow.
For new designs, this is a clean choice with no looming obsolescence risk.
If you are dual-sourcing, the ADM4853ARZ-REEL7 is the SOIC-8 variant with identical electrical specs; the ADM4853ARZ is the tube-packed version of that same die. Both are functional drop-ins if your board can accommodate the larger footprint.
