100325J-QMLV

Overview

The DS100325J-QMLV is a high-speed, low-power Schottky TTL quad bus driver manufactured by National Semiconductor (now Texas Instruments). It features four non-inverting buffers with tri-state outputs, designed for memory and chip-mapping applications. The device operates within a military temperature range of -55°C to +125°C and utilizes a ceramic dual in-line package (DIP) with 16 pins. It is qualified under the QMLV standard, ensuring reliability for demanding environments.

Feature Summary

• Provides four non-inverting buffers with tri-state output control for efficient data bus management.
• Constructed using high-speed Schottky TTL technology to minimize propagation delay and power consumption.
• Qualified to QMLV standards, ensuring compliance with rigorous military reliability requirements.
• Utilizes a hermetically sealed ceramic DIP package suitable for harsh operational conditions.

Applications

• Memory mapping systems requiring high-speed data transfer.
• Chip-to-bus driving interfaces in military avionics.
• High-reliability digital logic circuits operating in extreme temperatures.

Procurement Notes

Verify that the component carries the specific QMLV qualification marking, distinct from standard MIL-STD-883 Class B screening. Confirm the manufacturer source is National Semiconductor or authorized successor Texas Instruments. Ensure the ceramic package integrity is intact upon receipt. Request full traceability documentation including lot codes and test reports required for defense procurement compliance.

Selection Notes

Select this component when a quad bus driver with tri-state capability is required for high-speed digital interfacing. It is appropriate for designs needing Schottky TTL performance levels within a military-qualified ceramic package. Consider the 16-pin DIP form factor for through-hole mounting constraints. Verify voltage compatibility with existing TTL logic families in the system architecture.

Part Context

This part belongs to the DS100325 series of bus drivers, which are variants of the broader DS10000 family. These devices are engineered for high-speed data transmission in critical systems. The QMLV designation indicates a specific level of quality assurance and testing beyond standard commercial offerings, targeting aerospace and defense sectors.

Replacement Considerations

Check for direct equivalents such as the DS100325J without the QMLV suffix if environmental qualifications differ. Verify pinout compatibility with existing PCB layouts. Ensure that any substitute maintains the same Schottky TTL electrical characteristics and ceramic package dimensions.
