DS26LS32ACMX

Overview

The DS26LS32ACMX is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It complies with RS-422, RS-423, Federal Standards 1020 and 1030. The device operates on a single 5V supply (4.75V to 5.25V) within the commercial temperature range of 0°C to +70°C. It features TRI-STATE outputs with 8 mA sink capability, ±7V common-mode voltage range, and 200 mV input sensitivity. Input hysteresis is 100 mV, and typical propagation delay is 25 ns.

Feature Summary

• Compliant with RS-422 and RS-423 standards for balanced and unbalanced digital data transmission
• Features TRI-STATE outputs with selectable enable/disable functions for direct bus connection
• Includes internal pull-up and pull-down resistors to prevent output oscillation on unused channels
• Operates from a single 5V supply using low power Schottky processing

Applications

• Balanced digital data transmission systems
• Unbalanced digital data transmission systems
• RS-422 interface applications
• RS-423 interface applications

Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm package type, pin count, and environmental compliance. Confirm that the component status aligns with current design requirements, as availability may be limited for discontinued or lifecycle-managed parts.

Selection Notes

Select this component when designing systems requiring quad differential reception compliant with RS-422/RS-423 standards. Ensure the operating environment falls within the commercial temperature range of 0°C to +70°C and requires a single 5V supply. Verify that the SOIC-16 package fits the PCB layout constraints.

Part Context

This part belongs to the DS26LS32 family of quad differential line receivers produced by Texas Instruments. The 'AC' designation indicates the commercial temperature grade variant. The 'M' suffix specifies the SOIC surface-mount package, while 'X' denotes the tape-and-reel packaging format.

Replacement Considerations

DS26LS32CM/NOPB: Commercial grade, same package but tube packaging.
