100336J-QMLV

Overview

The 100336J-QMLV is a bidirectional shift register manufactured by National Semiconductor. It features four bits per element and operates with a supply voltage range of -4.2V to -5.7V. The device supports serial-to-parallel conversion functions and provides complementary output types. It is designed for operation within an extended temperature range of -55°C to 125°C. This component is classified as active logic with one element per package.

Feature Summary

• Bidirectional shift register functionality
• Serial to parallel data conversion capability
• Complementary output configuration

Applications

• Military aerospace systems requiring radiation tolerance
• Spacecraft data handling units
• High-reliability industrial control interfaces

Procurement Notes

Verify the manufacturer traceability and lot code against the specific QML (Qualified Military List) certification requirements. Confirm that the part status remains active and matches the exact suffix J-QMLV for environmental compliance. Request test reports ensuring performance within the specified -55°C to 125°C operating range. Validate the supply voltage compatibility with existing system power rails before procurement.

Selection Notes

Select this component when a qualified military-grade bidirectional shift register is required for harsh environments. Ensure the design accommodates the negative supply voltage range of -4.2V to -5.7V. Verify that the complementary output type meets the interface requirements of the downstream circuitry. Consider the thermal management needs for operation up to 125°C ambient temperature.

Part Context

This part belongs to the National Semiconductor 100336 series, which includes low-power counter and shift register devices. The QMLV designation indicates qualification under strict military standards, distinguishing it from commercial variants. The series is known for reliability in space and defense applications where standard commercial parts are unsuitable due to environmental constraints.

Replacement Considerations

Direct substitutes must match the QMLV qualification level. Check for equivalent parts from other manufacturers offering MIL-PRF-38534 or similar certifications. Ensure pinout compatibility and identical electrical specifications, particularly the negative supply voltage and temperature range.
