DS26C32ATM/NOPB

Overview

The DS26C32ATM/NOPB is a quad differential line receiver manufactured by Texas Instruments, designed for RS-422 bus communication. It operates on a single 5 V supply with a maximum operating current of 15 mA. The device supports data rates up to 10 Mb/s and features an SOIC-Narrow-16 surface-mount package. It complies with EIA/TIA-422-B, RS-422, and V.11 interface standards. The operational temperature range spans from -40 °C to +85 °C.

Feature Summary

• Provides four independent differential receivers for high-noise environments
• Compatible with standard RS-422 and EIA/TIA-422-B signaling protocols
• Operates reliably at data transfer speeds up to 10 Mb/s

Applications

• Industrial serial communication buses
• Data acquisition systems requiring differential input
• Telecommunications equipment interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for recent production change notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when a quad differential receiver is needed for 5 V RS-422 applications. Ensure the system design accommodates the 15 mA supply current and the SOIC-Narrow-16 footprint. Verify that the 10 Mb/s speed capability meets the network requirements.

Part Context

This part belongs to the DS26C32 family of CMOS quad differential receivers. It serves as a low-power alternative to older BiCMOS technologies in the AM26C32 series. The device is widely used in legacy and modern industrial control networks requiring robust differential signal integrity.

Replacement Considerations

The AM26C32M is a documented similar product offering lower power consumption. Verify compatibility with existing circuit designs before substitution.
