DS75176BN/NOPB

Overview

The DS75176BN/NOPB is a multipoint RS-485/RS-422 transceiver manufactured by Texas Instruments. It operates on a single +5V supply with a voltage range of 4.75V to 5.25V. The device supports data rates up to 10 Mb/s and features driver propagation delays of 22 ns typical. It provides a bus common mode range from -7V to +12V, allowing for ±7V ground differences between devices. The PDIP-8 package supports an operating temperature range of 0°C to +70°C. Electrical characteristics include a typical receiver hysteresis of 70 mV and a combined impedance of less than one RS-485 unit load.

Feature Summary

• Supports multipoint data transmission on balanced lines with extended common mode range.
• Features thermal shutdown protection and high impedance state during power-off or tri-state conditions.
• Allows up to 32 transceivers on the bus due to low combined input/output impedance.

Applications

• Multipoint bus transmission in noisy environments
• Industrial control systems requiring RS-485 compatibility
• Building automation networks

Procurement Notes

Verify the specific ordering suffix 'BN' against current TI documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in the Package Option Addendum. Check for lifetime buy availability if long-term supply is required. Ensure the supplier provides original manufacturer packaging to prevent handling damage.

Selection Notes

Select this component for applications requiring half-duplex communication over long bus lines. Compare with SN75176B for pin-compatible alternatives. Verify that the 0°C to +70°C industrial temperature range meets system requirements. Consider the DS75176BT variant if operation below 0°C is necessary.

Part Context

This part belongs to the DS75176B family of differential bus transceivers. It is designed for bidirectional data communication on multipoint bus transmission lines. The device is compatible with EIA standard RS-485 and RS-422 specifications. It serves as a robust interface solution for industrial and commercial serial communication networks.

Replacement Considerations

SN75176B is a pin-compatible alternative within the same functional family. DS75176BT offers the same functionality but with an extended temperature range of -40°C to +85°C. Verify electrical parameters match before substitution.
