DS26C32ATMX/NOPB

Overview

The DS26C32ATMX/NOPB is a quad differential line receiver manufactured by Texas Instruments, designed for high-speed data transmission. It complies with EIA/TIA-422-B and ITU-T V.11 standards. The device operates on a single 5V supply voltage, with a minimum of 4.5V and maximum of 5.5V. It features four receivers with differential inputs and TTL-compatible outputs. The typical operating supply current is 15 mA. It supports data rates up to 32 MHz switching frequency. The component is housed in a 16-pin SOIC-Narrow package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Quad differential input architecture supporting RS-422 communication protocols
• TTL-compatible output levels ensuring interoperability with standard logic families
• Enhanced CMOS design providing low power consumption suitable for battery-operated systems
• Common-mode noise rejection capabilities with defined fault-safe behavior

Applications

• Industrial serial communication networks requiring RS-422 compliance
• Data acquisition systems utilizing differential signaling for noise immunity
• Telecommunications equipment interfacing with V.11 standard lines
• Embedded control systems needing low-power bus receivers

Procurement Notes

Verify the specific suffix NOPB indicates lead-free and RoHS compliance status against the latest manufacturer datasheet. Confirm the SOIC-Narrow-16 package dimensions match PCB footprint requirements. Check for obsolescence notices or lifecycle changes from Texas Instruments prior to finalizing procurement plans.

Selection Notes

Select this component when a quad receiver with 5V operation is required instead of 3.3V variants like the DS26LV32A. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the 15 mA supply current aligns with system power budget constraints compared to lower-power alternatives.

Part Context

This part belongs to the DS26C32AT family of bus receivers. It serves as a complementary component to drivers such as the DS26C32AMX. The device is distinct from LVDS receivers due to its higher voltage operation and TTL output compatibility. It is widely used in legacy and industrial interfaces where robustness over long cable runs is critical.

Replacement Considerations

The DS26C32ATMX/NOPB is functionally pin-compatible with the NSC DS26C32ATMX. Direct replacements include other manufacturers' RS-422 quad receivers meeting EIA/TIA-422-B specifications. Verify electrical parameters such as propagation delay and common-mode range before substituting.
