DS75176BTMX

Overview

The DS75176BTMX is a multipoint RS-485/RS-422 transceiver manufactured by Texas Instruments. It operates on a single +5V supply and supports data rates up to 10 Mb/s. The device features TRI-STATE outputs with a common mode range of -7V to +12V, allowing for ±7V ground differences between devices. It includes thermal shutdown protection and meets EIA Standard RS485 requirements. The component is housed in an SOIC-8 package and is rated for operation from -40°C to +85°C.

Feature Summary

• Supports multipoint bus transmission compatible with RS-485 and RS-422 standards.
• Features TRI-STATE driver and receiver outputs for bus contention handling.
• Includes thermal shutdown circuitry to protect against excessive power dissipation.
• Provides extended common mode range to accommodate significant ground differences.

Applications

• Multipoint data transmission systems requiring RS-485 compliance.
• Industrial communication networks utilizing differential signaling.
• Bus line transceivers designed for half-duplex data exchange.

Procurement Notes

Verify the specific ordering suffix to confirm the presence of lead-free (NOPB) packaging and RoHS compliance status. Confirm the current lifecycle status as LIFEBUY or OBSOLETE before finalizing procurement plans. Ensure that the SOIC-8 tape and reel quantity matches the required production volume. Check for any specific environmental certifications required by the target application.

Selection Notes

Select this component when an industrial temperature range of -40°C to +85°C is required. Choose the DS75176BTMX over the standard DS75176BM variant if extended temperature performance is necessary. Ensure the design accommodates the 10 Mb/s maximum data rate capability. Verify that the system voltage remains within the 4.75V to 5.25V operating window.

Part Context

This part belongs to the DS75176B family of multipoint transceivers. It shares pinout compatibility with the SN75176A/B and DS3695/A series. The 'BTM' designation indicates the extended temperature grade and surface-mount SOIC-8 packaging. The 'X' suffix specifies the tape and reel packaging format for automated assembly.

Replacement Considerations

The DS75176BM/NOPB serves as a commercial grade alternative but lacks the extended temperature rating. The SN75176BD offers similar functionality in a different package style. Verify thermal management requirements when substituting components with different power dissipation characteristics.
