54LS122/BDA

Overview

The 54LS122/BDA is a dual-marked monostable multivibrator manufactured by Rochester Electronics, LLC. It corresponds to the military specification M38510/31403BDA. The device operates within a temperature range of -55 °C to 125 °C and utilizes TTL logic technology. It is designed for generating precise single pulses in response to external triggering events.

Feature Summary

• Monostable multivibrator functionality for pulse generation
• Military-grade reliability under M38510/31403BDA specification
• Extended industrial temperature operation capability

Applications

• Timing circuits requiring precise pulse width control
• Debouncing switches or contacts
• Pulse stretching applications

Procurement Notes

Verify the dual marking M38510/31403BDA on the component surface to confirm authenticity. Ensure the supplier provides traceability documentation linking the part to the original military specification. Confirm that the package type matches the required form factor for your assembly process before finalizing the order.

Selection Notes

Select this component when a robust, military-specification monostable multivibrator is required for harsh environments. Consider the extended temperature range if the application operates outside standard commercial limits. Verify that the TTL input compatibility aligns with the driving circuitry in the design.

Part Context

This part belongs to the LS series of logic devices, known for low-power Schottky characteristics. Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find components, often providing military-grade parts that have reached end-of-life status from original manufacturers.

Replacement Considerations

Direct substitutes include other M38510/31403BDA variants from authorized distributors. Cross-reference with generic 54LS122 equivalents only if military qualification is not strictly required and pinout compatibility is confirmed.
