DS26LS32ACMX/NOPB

Overview

The DS26LS32ACMX/NOPB is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It meets RS-422, RS-423, Federal Standards 1020 and 1030 requirements. The device operates from a single 5V supply with a voltage range of 4.75V to 5.25V. It features TRI-STATE outputs with 8mA sink capability and includes input pull-up/pull-down resistors to prevent oscillation on unused channels. Operating temperature ranges from 0°C to +70°C. It is housed in a 16-pin SOIC package.

Feature Summary

• Quad differential line receivers meeting RS-422 and RS-423 standards
• TRI-STATE outputs with 8 mA sink capability
• Input pull-up and pull-down resistors prevent output oscillation on unused channels
• High common-mode voltage range of ±7V

Applications

• Balanced digital data transmission systems
• Unbalanced digital data transmission systems
• RS-422 interface applications

Procurement Notes

Verify the LIFEBUY status before procurement as the device is discontinued. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure compatibility with existing system designs due to end-of-life status. Check for availability through authorized distributors during the lifetime-buy period.

Selection Notes

Select this component for applications requiring quad differential reception compliant with RS-422/RS-423 standards. Consider the commercial temperature range (0°C to +70°C) and 5V supply requirement. Evaluate the need for TRI-STATE outputs and unused channel protection features. Verify package availability given the discontinuation status.

Part Context

This part belongs to the DS26LS32 family of quad differential line receivers. It shares functional similarities with the DS26LS32C and DS26LS32M variants but differs in operating temperature range and specific electrical characteristics. The 'AC' designation indicates the commercial temperature grade variant within the series.
