DS90C032 MDR

Overview

The DS90C032 MDR is a quad CMOS differential line receiver manufactured by Texas Instruments, designed for high-speed point-to-point interface applications. It accepts low voltage differential signaling (LVDS) inputs and translates them to CMOS-compatible output levels. The device operates within a supply voltage range of +4.5V to +5.5V and supports an operating free air temperature from -55°C to +125°C. Key electrical parameters include a differential propagation delay of 1.0 ns to 8.0 ns, a maximum differential skew of 3.0 ns, and a chip-to-chip skew of 7.0 ns. The no-load supply current is specified at 11 mA with inputs open.

Feature Summary

• Single Event Latchup (SEL) immune up to 120 MeV-cm²/mg
• High impedance LVDS inputs that maintain functionality during power-off conditions
• Supports TRI-STATE function for output multiplexing
• Compatible with IEEE 1596.3 standard LVDS inputs

Applications

• High speed point-to-point interface applications
• Replacement for high power pseudo-ECL devices
• Radiation environments requiring Total Ionizing Dose assurance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm the exact package type, such as Die Sale or Ceramic Flatpack, and ensure the material type matches production requirements. Confirm radiation qualification status if the application demands MIL-STD-883 compliance. Check the active production status directly on the official product page before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require radiation tolerance and high-speed data reception in harsh environments. Ensure the system design accommodates the required 100Ω termination near the receiver inputs. Verify that the ambient temperature range aligns with the -55°C to +125°C specification. Consider external failsafe biasing if the application involves terminated inputs in high noise environments.

Part Context

This device belongs to the DS90C032QML family, which includes variants like the DS90C032E-QML and DS90C032W-QMLV. These parts are qualified for military and space applications under QML standards. The MDR suffix specifically denotes the Die Sale format, distinguishing it from packaged versions like LCCC or CFP found in the same series.

Replacement Considerations

Public confirmed substitute part numbers include DS90C032E-QML and DS90C032W-QMLV. Verify pin compatibility and radiation hardness specifications before substitution.
