Key Features
- RS-485 and RS-422 compatible differential line transceiver with Schmitt trigger inputs for improved noise immunity on long industrial cable runs
- Common I/O bus architecture with tri-state receiver and 1 receiver remaining active under shutdown for fail-safe bus monitoring
- SOIC-8 package operating on a 5 V supply, enabling drop-in integration into existing RS-485 multi-drop networks with up to 32 unit loads
Applications
The DS75176BTM is used in industrial RS-485 multi-drop networks for PLCs, DCS field devices, and building automation controllers where reliable half-duplex communication over cable runs of up to 1200 m is required. Its differential Schmitt trigger input rejects common-mode noise from motor drives and other EMI sources on the factory floor, ensuring robust data integrity at baud rates up to 10 Mbps. The device is also suitable for RS-422 point-to-point links in instrumentation and test equipment requiring balanced differential signal transmission.

Frequently Asked Questions
What interface standards does DS75176BTM support, and at what maximum baud rate?
The DS75176BTM supports both EIA-485 (RS-485) and EIA-422 (RS-422) interface standards and can operate at data rates up to 10 Mbps, making it suitable for high-speed industrial automation networks and instrumentation links over twisted-pair cables.
How does the Schmitt trigger input on DS75176BTM improve noise immunity in factory environments?
The differential Schmitt trigger input provides hysteresis on the received differential signal, rejecting slow-rising noise and common-mode transients of up to ±7 V generated by nearby motor drives, contactors, and power cables. This prevents spurious data errors on RS-485 bus segments running alongside high-current industrial wiring over cable lengths up to 1200 m.
What happens to the DS75176BTM receiver when the device is put into shutdown mode?
One receiver remains active during shutdown, allowing the device to continue monitoring bus traffic for bus-idle or wake-up conditions without drawing full operating current. This feature is useful in energy-sensitive RS-485 nodes that must respond to network events while keeping supply current below 1 mA during inactive periods.
How many devices can share the same RS-485 bus with DS75176BTM in a multi-drop network?
Each DS75176BTM presents 1 unit load to the RS-485 bus. The EIA-485 standard allows up to 32 unit loads per segment, meaning up to 32 DS75176BTM transceivers can be connected to a single differential 120-ohm terminated bus segment before bus loading degrades signal integrity below specification limits.
