DS26LS32ACN

Overview

The DS26LS32ACN is a quad differential line receiver manufactured by Texas Instruments, which acquired National Semiconductor. It complies with RS-422 and RS-423 standards for serial data transmission. The device integrates four independent receivers in a single package. It operates within a supply voltage range of 4.5 V to 5.5 V. The maximum data rate supported is 10 Mb/s. The quiescent supply current is typically 52 mA. The component is housed in a 16-pin PDIP package designed for through-hole mounting. It functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides four independent differential receivers for high-speed serial communication
• Complies with EIA/TIA-422-B and RS-423-A interface standards
• Features low noise input circuitry for reliable signal detection

Applications

• RS-422 balanced digital interface circuits
• RS-423 unbalanced digital interface circuits
• Industrial control systems requiring differential signaling
• Data acquisition systems with long cable runs

Procurement Notes

Verify the manufacturer designation carefully, as the part was originally produced by National Semiconductor before its acquisition by Texas Instruments. Confirm that the specific suffix indicates the commercial grade variant suitable for the required thermal environment. Ensure the procurement source provides authentic components matching the original National Semiconductor specifications.

Selection Notes

Select this component when a quad receiver configuration is required for RS-422 or RS-423 networks. It is appropriate for designs needing through-hole packaging for robust mechanical connections. Consider alternative packages if surface-mount technology is preferred for automated assembly processes.

Part Context

This component belongs to the DS26LS32 family of quad differential line receivers. It serves as a standard interface solution for converting differential signals into single-ended logic levels. The device is widely used in legacy and industrial equipment where RS-422 compatibility is essential for noise immunity over moderate distances.

Replacement Considerations

The AM26LS32ACN is a functionally equivalent replacement offering identical electrical characteristics. Other compatible variants include the DS26LS32C for extended temperature ranges and the DS26LS32M for military specifications.
