What are the key features of ADM489ARUZ?
- Half-duplex RS-485/RS-422 transceiver supporting data rates up to 12 Mbps for high-speed industrial serial networks
- Differential Schmitt trigger receiver input improves noise rejection on long cable runs over 1200 m
- Wide supply voltage range of 3 V to 5.5 V enables use in both 3.3 V and 5 V system designs
- 16-pin TSSOP (MO-153AB) package reduces PCB footprint in space-constrained industrial equipment
What is ADM489ARUZ used for?
The ADM489ARUZ is ideal for industrial automation networks such as PROFIBUS, Modbus RTU, and RS-485 multi-drop buses where up to 32 nodes must communicate reliably over cable lengths up to 1200 m. It is also used in building automation controllers, motor drive systems, and programmable logic controllers that require robust differential signaling at data rates up to 12 Mbps. Its Schmitt trigger input and wide supply range make it a robust choice for factory-floor environments with high electrical noise.

Frequently Asked Questions
How many nodes can share a single RS-485 bus when using ADM489ARUZ transceivers?
The ADM489ARUZ is specified for RS-485 networks supporting up to 32 unit loads on a single bus segment, allowing up to 32 transceivers to communicate across cable lengths reaching 1200 m. With a high-impedance receiver input drawing no more than 1 µA, multiple ADM489ARUZ devices can be tied together without overloading the differential bus, making it practical for large multi-drop industrial control systems.
What data rate does ADM489ARUZ achieve, and how does it compare to standard RS-485 requirements?
The ADM489ARUZ supports a maximum data rate of 12 Mbps, which is 24 times higher than the standard RS-485 baseline of 500 kbps at 1200 m. At shorter cable lengths below 40 m, this 12 Mbps rate enables high-throughput sensor polling and real-time motion control feedback loops. The device's differential Schmitt trigger input with 200 mV hysteresis maintains signal integrity even at these higher speeds.
Is ADM489ARUZ suitable for 3.3 V microcontroller systems used in embedded industrial designs?
Yes, the ADM489ARUZ operates from a supply voltage as low as 3 V, making it directly compatible with 3.3 V microcontrollers common in embedded ARM Cortex-M and RISC-V designs. Its logic-level inputs accept signals as low as 2 V, so no level-shifting is needed when interfacing with 3.3 V MCU UART pins. The device can also run from 5 V supplies, providing flexibility across both legacy 5 V and modern 3.3 V system architectures.
