DS9637ACM

Overview

The DS9637ACM is a dual differential line receiver manufactured by Texas Instruments, designed to meet EIA RS-422 and RS-423 standards. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V. The device features Schottky technology for high-speed performance, supporting propagation delays of up to 25ns. It includes built-in ±35mV hysteresis and an input common mode voltage range of ±7V. The component is housed in an 8-lead SOIC package and supports an industrial operating temperature range from 0°C to +70°C.

Feature Summary

• Dual-channel architecture providing two independent receivers within a single integrated circuit
• Schottky TTL compatible outputs ensuring compatibility with standard logic families
• High input impedance and wide common mode voltage range for robust signal reception
• Built-in hysteresis to improve noise immunity during data transmission

Applications

• Digital data systems utilizing differential transmission lines
• RS-422 compliant serial communication interfaces
• Industrial control networks requiring MIL-STD 188-114 compliance

Procurement Notes

Verify the specific suffix 'CM' corresponds to the commercial temperature grade (0°C to +70°C) and SOIC-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design safeguards account for limited ESD protection inherent to the MOS gates.

Selection Notes

Select this component when RS-422 compatibility and Schottky speed are required within a commercial temperature environment. Compare against the DS9637AM variant if extended military temperature ranges (-55°C to +125°C) are necessary. Verify that the 5V supply constraint aligns with the target system power architecture.

Part Context

This device belongs to the DS9637A family of dual differential line receivers. It shares core functional specifications with variants such as the DS9637AD and DS9637AP, differing primarily in packaging style and specified temperature operating ranges defined by their respective ordering suffixes.

Replacement Considerations

The DS9637ACDR serves as a reel-based surface-mount alternative within the same product family. Cross-referencing with the UA9637A series may be considered for similar RS-422 functionality, though electrical parameters should be validated against specific application requirements.
