DS91C176TMA-NS

Overview

The DS91C176TMA-NS is a single-channel Multipoint-LVDS (M-LVDS) transceiver manufactured by National Semiconductor. It integrates one driver and one receiver in an 8-pin SOIC package, supporting data rates up to 200 Mb/s with a typical operating frequency of 100 MHz. The device operates on a supply voltage range of 3.0 V to 3.6 V, drawing approximately 29.5 mA during operation. It functions within an industrial temperature range of -40°C to +85°C and exhibits a propagation delay of 7.5 ns. This component facilitates high-speed serial communication compatible with LVCMOS, LVTTL, and M-LVDS input/output standards.

Feature Summary

• Supports Multipoint-LVDS (M-LVDS) signaling for robust long-distance transmission
• Integrates a single half-duplex driver and receiver pair
• Compatible with standard logic families including LVCMOS and LVTTL

Applications

• High-speed serial data links requiring multipoint topology
• Industrial control systems and automation networks
• Test and measurement equipment interfaces

Part Context

This component belongs to the DS91C176 series of M-LVDS transceivers originally developed by National Semiconductor before its acquisition by Texas Instruments. The 'TMA' suffix indicates an 8-pin SOIC plastic package, while '-NS' denotes the original National Semiconductor manufacturer code. These devices are designed to replace traditional LVDS components where multipoint capability is required.

Replacement Considerations

Texas Instruments lists the DS91C176TMAX/NOPB as a direct successor part number within the same family. Designers should verify that the pinout and electrical characteristics remain identical when transitioning from the National Semiconductor version to the TI-manufactured equivalent.
