9601FMQB

Multivibrators Overview

The National Semiconductor 9601FMQB is a monostable multivibrator integrated circuit manufactured using TTL technology. It features a ceramic dual flatpack (DFP) package with 14 terminals and a 1.27 mm pin pitch. The device operates on a nominal 5 V supply voltage and is qualified for military temperature ranges, supporting operation from -55 °C to 125 °C. It meets MIL-STD-38535Q/M, MIL-STD-38534H, and MIL-STD-883B screening levels.

Multivibrators Feature Summary

• Monostable multivibrator functionality within a TTL logic family
• Military-grade qualification compliant with MIL-STD-38535/34 and MIL-STD-883 standards
• High-temperature operational capability suitable for extreme environments

Multivibrators Applications

• Military aerospace electronic systems
• Harsh environment signal processing circuits
• TTL-based timing pulse generation

Multivibrators Procurement Notes

Verify the manufacturer origin carefully, as the part number prefix may indicate Twilight Technology Inc rather than National Semiconductor in some databases. Confirm that the specific suffix FMQB corresponds to the ceramic flatpack package and military screening level required for your application. Ensure compatibility with existing TTL logic families and power supply requirements before procurement.

Multivibrators Selection Notes

Select this component when a ruggedized, military-specification monostable multivibrator is required for high-temperature applications. The TTL technology ensures compatibility with standard digital logic interfaces. Consider the ceramic packaging for superior thermal and mechanical stability compared to plastic alternatives in demanding operational conditions.

Multivibrators Part Context

This component belongs to the broader category of monostable multivibrators used for generating single output pulses. While originally associated with National Semiconductor, similar parts are also documented under Twilight Technology Inc, indicating potential manufacturing or distribution overlaps in the military electronics sector.

Multivibrators Replacement Considerations

Direct substitutes include other military-grade TTL monostable multivibrators in DFP packages. Verify pinout compatibility and electrical specifications against equivalents such as those from Texas Instruments or Analog Devices that meet MIL-STD-883 requirements.
