JM38510/31402BFA

Multivibrators Overview

The JM38510/31402BFA is a dual monostable multivibrator from the LS series, manufactured by Texas Instruments. It features Schmitt-trigger inputs and operates within a temperature range of -55°C to 125°C. The device utilizes a 16-lead ceramic flatpack (CFP) package. Electrical specifications include a maximum low-level output current of 8 mA and a high-level output current of -0.4 mA. It is designed for TTL logic compatibility.

Multivibrators Feature Summary

• Dual monostable multivibrator configuration with independent timing circuits
• Schmitt-trigger inputs for noise immunity and clean signal triggering
• Military-grade temperature range capability from -55°C to 125°C
• Ceramic flatpack construction for durability in harsh environments

Multivibrators Applications

• Timing pulse generation in military avionics systems
• Debouncing switches in ruggedized electronic equipment
• One-shot pulse width modulation circuits
• Frequency division and waveform shaping in communication hardware

Multivibrators Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact electrical tolerances and radiation hardness levels. Ensure the component matches the required MIL-PRF-38534 quality level. Confirm package integrity and pin alignment prior to integration into sensitive aerospace or defense assemblies.

Multivibrators Selection Notes

Select this component when dual independent monostable operation is required in extreme thermal conditions. The Schmitt-trigger input distinguishes it from standard TTL variants lacking hysteresis. Consider the CFP package constraints for board layout and thermal management requirements in enclosed military enclosures.

Multivibrators Part Context

This part belongs to the SN54LS221 family, representing a military-specification version of the commercial SN74LS221. It adheres to strict reliability standards defined by MIL-PRF-38534. The device serves as a robust alternative to commercial logic families in applications demanding extended temperature stability and long-term operational reliability.

Multivibrators Replacement Considerations

Direct equivalents include the SN54LS221J and SN54LS221FK. Verify that substitute parts meet the same ceramic package and military temperature grade requirements. Cross-reference datasheets to ensure identical pinout and electrical characteristics before implementation.
