DS26LS32CN

Overview

The DS26LS32CN is a quad differential line receiver manufactured by National Semiconductor, now part of Texas Instruments. It complies with EIA-422 and TIA-422-B standards for serial data transmission. The device features four independent receivers capable of operating at data rates up to 10 Mb/s. It functions within a supply voltage range of 4.75 V to 5.25 V, with a typical operating current of 70 mA. The component is housed in a 16-pin DIP package and supports an industrial temperature range from 0°C to +70°C.

Feature Summary

• Provides four independent differential line receivers compliant with RS-422 standards.
• Supports high-speed data transmission with a maximum rate of 10 Mb/s.
• Operates on a standard 5 V power supply with defined minimum and maximum voltage limits.

Applications

• Serial communication interfaces requiring RS-422 compliance.
• Industrial control systems utilizing differential signaling for noise immunity.
• Data acquisition networks connecting multiple nodes over balanced lines.

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official documentation, as legacy parts may have varying environmental certifications depending on production batch and date code.

Selection Notes

Select this component when a quad receiver configuration is required for RS-422 applications. Compare against the AM26LS32AC series for potential pin-compatible alternatives offered by Texas Instruments. Evaluate thermal requirements to ensure the 0°C to +70°C range meets system specifications. Verify that the 10 Mb/s speed capability aligns with the network's timing constraints.

Part Context

This device belongs to the DS26LS32 family of quad differential line receivers. It serves as a core interface component for converting differential signals to single-ended logic levels. The CN suffix typically denotes a plastic dual in-line package (DIP) variant suitable for through-hole mounting. It is functionally related to other devices in the DS26C32 and AM26LS32 families.

Replacement Considerations

The AM26LS32ACDR or AM26LS32ACNSR are direct functional equivalents from Texas Instruments. These replacements offer identical electrical characteristics and pinouts. Verify package compatibility, as the AM26LS32AC is also available in SOIC and SOP formats.
