DS26LV32ATMX

Overview

The DS26LV32ATMX is a quad differential line receiver manufactured by Texas Instruments, designed for high-speed data transmission. It operates on a single 3.3V supply with a typical static current of 9 mA and maximum of 15 mA within the -40°C to +85°C industrial temperature range. The device supports up to 32 MHz toggle frequency and features a ±7V common mode range at VID = 3V. Outputs are compatible with TTL and LVCMOS levels, while inputs tolerate signals as low as ±200 mV over a ±10V common mode range. It includes tri-state enables (EN, EN*) and an open-input failsafe feature ensuring a high output state when inputs are unconnected.

Feature Summary

• Compliant with TIA/EIA-422-B and ITU-T V.11 standards for RS-422 networks
• Low power CMOS design suitable for battery-powered applications
• Tri-state outputs with common enable controls for all four receivers
• Open input failsafe mechanism guarantees high logic level during disconnection

Applications

• Industrial communication systems requiring RS-422 compliance
• Battery-operated electronic devices prioritizing low power consumption
• High-speed data buses operating up to 32 MHz

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for lifetime buy availability due to discontinuation notices. Validate package markings against official datasheet specifications to ensure correct revision and origin before integration into production lines.

Selection Notes

Select this component for designs requiring quad differential reception with 3.3V logic compatibility. Ensure system voltage remains within 3.0V to 3.6V limits. Consider thermal dissipation requirements if operating near maximum temperature boundaries. Verify that load capacitance does not exceed specified limits to maintain signal integrity at high frequencies.

Part Context

This part belongs to the DS26LV32A family of enhanced CMOS receivers. It serves as a pin-compatible alternative to older bipolar technologies like the DS26C32AT. The MX suffix indicates tape and reel packaging for automated assembly processes, distinguishing it from tube-packaged variants.

Replacement Considerations

DS26LV32ATM/NOPB offers identical electrical characteristics in tube packaging.
