UA9637ACD

Drivers, Receivers, Transceivers Overview

The UA9637ACD is a dual differential line receiver manufactured by Texas Instruments, designed to meet ANSI EIA/TIA-422-B and EIA/TIA-423-B standards. It operates from a single 5V power supply with a recommended range of 4.75V to 5.25V. The device features high-speed Schottky circuitry and TTL-compatible outputs. It supports a wide common-mode input voltage range of ±7V and includes two independent receivers in an 8-pin SOIC package. Propagation delays are typically 15ns to 25ns at VCC=5V and CL=30pF. The component is characterized for operation between 0°C and 70°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix when sourcing this component, as it determines the packaging format and production status. The base model UA9637ACD is listed as obsolete in official documentation. Active alternatives include variants with 'R' or 'E4' suffixes which utilize tape-and-reel packaging. Confirm moisture sensitivity levels and lead finish specifications against current project requirements before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring RS-422/RS-423 compliant differential reception with TTL output compatibility. Ensure the system operates within the 0°C to 70°C temperature range and utilizes a 5V power supply. Consider active package variants if reel-based manufacturing is required. Verify thermal dissipation ratings against the expected ambient conditions and board layout constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the uA9637A family of dual differential line receivers. It is functionally interchangeable with the National Semiconductor DS9637A. The family includes various package options such as SOIC, PDIP, and SOP, catering to different assembly needs while maintaining identical electrical performance characteristics across the series.

Drivers, Receivers, Transceivers Replacement Considerations

The UA9637ACD is marked as obsolete. Active replacements include UA9637ACDR, UA9637ACDRG4, and UA9637ACDRE4. These variants offer the same electrical specifications but differ in packaging (tape-and-reel) and environmental compliance markings.
