DS26LV32ATM

Overview

The DS26LV32ATM is a low-power CMOS quad differential line receiver designed for high-speed data transmission. It operates on a single 3.0V to 3.6V supply with a typical quiescent current of 9 mA at 3.3V. The device supports a maximum toggle frequency of 32 MHz and features a common-mode input range of ±7V at VID = 3V, extending to ±10V at VID = 0.2V. Outputs are TRI-STATE compatible with TTL and LVCMOS levels. It includes an open-input failsafe feature that guarantees a high output state when inputs are left unconnected. The component is housed in a 16-pin SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports TIA/EIA-422-B and ITU-T V.11 standards for interoperability with existing RS-422 networks.
• Features TRI-STATE outputs enabled by common EN and EN* pins for bus organization.
• Includes receiver open-input failsafe to ensure a high logic level during unterminated conditions.

Applications

• High-speed serial data communication systems requiring RS-422 compliance.
• Battery-powered applications benefiting from low static power consumption.
• Bus-oriented network topologies utilizing TRI-STATE output capabilities.

Procurement Notes

Verify the specific ordering suffix against the latest Texas Instruments Package Option Addendum to confirm availability status and environmental compliance. The base model may be designated as LIFEBUY or ACTIVE depending on the tape-and-reel configuration. Ensure the selected variant matches the required operating temperature range and packaging specifications for the target application design.

Selection Notes

Select this component for designs requiring a quad differential receiver with low power dissipation and wide common-mode tolerance. Verify that the system voltage remains within the 3.0V to 3.6V range to maintain specified electrical characteristics. Consider the 32 MHz maximum toggle frequency limit when designing for high-speed signal integrity requirements.
