DS36276MX/NOPB

Overview

The DS36276MX/NOPB is a half-duplex RS-485 transceiver in an 8-pin SOIC package. It operates at a supply voltage of 5 V and supports data rates up to 20 Mb/s. The device features a failsafe receiver that guarantees a HIGH output state during floating, idle, or fault conditions. It provides a wide bus common-mode range from −7 V to +12 V and includes short-circuit protection for both the driver and receiver outputs.

Feature Summary

• Guarantees a known HIGH receiver output state when inputs are open, terminated, or shorted
• Supports multipoint transmission on bi-directional differential buses
• Provides independent control signals for driver enable, receiver enable, and data input/output

Applications

• Asynchronous controllers such as UARTs requiring reliable line status detection
• Multipoint communication networks adhering to TIA/EIA-485 standards
• Systems utilizing CCITT Recommendation V.11 interface protocols

Procurement Notes

Verify the specific suffix 'NOPB' against the manufacturer's current documentation to confirm lead-free compliance and RoHS status. Ensure the ordering information matches the exact package style and temperature grade required for your design specifications before finalizing procurement.

Selection Notes

Select this component when a guaranteed logic state is required during bus faults or disconnection events. It serves as a pin-compatible replacement for legacy devices like the SN75176A/B and DS75176B. Confirm that the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the DS36276 family of failsafe multipoint transceivers. It is manufactured by Texas Instruments and maintains backward compatibility with standard RS-485 interfaces while adding robust fault protection features not found in basic transceivers.

Replacement Considerations

Pin-compatible substitutes include the DS75176B, DS96176, DS3695, SN75176A, and SN75176B.
