UA9638CIDREP

Drivers, Receivers, Transceivers Overview

The UA9638CIDREP is a dual high-speed differential line driver from the UA9638C series, manufactured by Texas Instruments. It functions as an RS-422 interface integrated circuit designed for robust signal transmission in noisy environments. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 10 Mb/s. It is housed in an 8-pin SOIC package with surface-mount installation. The component is qualified for extended industrial temperature ranges, functioning reliably between -40°C and +85°C. This specific part number denotes the tape-and-reel packaging variant of the UA9638C.

Drivers, Receivers, Transceivers Feature Summary

• Dual differential line drivers for RS-422 communication protocols
• High-speed data transmission capability up to 10 Mb/s
• Extended industrial operating temperature range for harsh environments

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable serial communication
• Embedded CompactRIO single-board controllers such as the sbRIO-9638
• OEM applications needing flexible and high-performance digital I/O interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. The UA9638CIDREP specifically indicates the reel packaging format. Confirm that the required operating temperature range matches the -40°C to +85°C specification. Ensure compatibility with 5V logic levels and RS-422 protocol requirements before integration into the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual transmitter solution is required for RS-422 networks without the need for receivers. Compare against the UA9639CP if receiver functionality is needed instead. Consider the SOIC-8 package constraints for PCB layout. Verify that the 10 Mb/s speed meets the system's bandwidth requirements. Check for alternative packages if through-hole mounting is preferred over surface mount.

Drivers, Receivers, Transceivers Part Context

This component belongs to the UA9638C family of high-speed differential line drivers. It serves as the transmitter counterpart to receiver devices like the UA9639. The 'EP' designation often implies enhanced performance or qualification standards, while 'IDREP' specifies the industrial temperature grade and reel packaging. It is commonly used in embedded controller boards for data acquisition and control tasks.

Drivers, Receivers, Transceivers Replacement Considerations

The UA9638CDR is a standard commercial-grade equivalent in the same SOIC-8 package but lacks the extended temperature rating. For pin-compatible alternatives, verify datasheet specifications carefully as functional differences may exist between driver-only and transceiver ICs.
