DS90C032WGLQMLV

Overview

The DS90C032WGLQMLV is a quad CMOS differential line receiver designed for high-speed point-to-point interfaces. It translates low voltage differential signals to CMOS output levels while maintaining ultra-low power dissipation. The device supports data rates up to 155.5 Mb/s with a typical propagation delay of 1.0 ns and maximum skew of 7.0 ns. It operates on a single +4.5V to +5.5V supply, drawing 11 mA under no-load conditions. The component features TRI-STATE functionality for bus multiplexing and includes internal failsafe circuitry for open inputs.

Feature Summary

• Single Event Latchup (SEL) immune up to 120 MeV-cm²/mg
• High impedance LVDS inputs that remain active during power-off states
• Internal failsafe biasing ensures HIGH output state for floating inputs
• Pin compatible with the DS26C32A standard

Applications

• Military and defense applications requiring radiation tolerance
• Space-based systems utilizing ceramic packaging
• High-speed point-to-point interface links
• Systems replacing pseudo-ECL devices for lower power consumption

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm the exact package type and material specifications. Ensure the procurement channel provides documentation confirming QML certification status if required for military or space-grade compliance. Cross-reference the part marking code with the official datasheet to validate authenticity and traceability before integration into production.

Selection Notes

Select this component when radiation hardness and low power consumption are critical constraints. It serves as a direct replacement for pseudo-ECL receivers in high-speed digital designs. Verify that the system environment does not exceed the specified common-mode input voltage range of 0V to +2.4V. Consider external biasing requirements if the application involves terminated lines subject to potential noise interference exceeding 10mV differential levels.

Part Context

This device belongs to the DS90C032QML family, which is specifically qualified for military and space environments. It complements the DS90C031 line driver to form a complete LVDS interface solution. The QML designation indicates adherence to strict quality conformance inspection standards, ensuring reliability in harsh operational conditions where standard commercial components would fail.

Replacement Considerations

The DS90C032WGLQMLV is pin-compatible with the DS26C32A. For equivalent radiation-hardened performance, consider the DS90C032E-QML or DS90C032WLQMLV variants, depending on the required ceramic flatpack configuration.
