JM38510/31512BFA

Counter Dividers Overview

The JM38510/31512BFA is a military-grade synchronous 4-bit binary counter manufactured by Texas Instruments. It implements the SN54LS163A logic function within a 16-pin ceramic flatpack (CFP) package. The device operates on a single supply voltage of 5V, with an acceptable range of 4.5V to 5.5V. It features a positive-edge-triggered clock input and supports parallel data loading. The component is designed for high reliability in harsh environments, operating across a temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture with dedicated load control
• Military-grade construction utilizing hermetic ceramic packaging
• Positive-edge triggered clocking mechanism for precise timing synchronization

Counter Dividers Applications

• High-reliability digital counting systems
• Military aerospace timing circuits
• Industrial process control counters

Counter Dividers Procurement Notes

Verify the specific suffix 'BFA' against official Texas Instruments documentation to confirm the exact pinout and package variant. Ensure that the procurement channel provides traceable military-grade components suitable for the required environmental specifications. Confirm compliance with relevant defense standards before finalizing acquisition.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with parallel load capability is required for ruggedized applications. The LS logic family offers a balance of speed and power consumption. Consider the CFP package dimensions and thermal properties during PCB layout to ensure proper mounting and heat dissipation within the specified operational temperature limits.

Counter Dividers Part Context

This part belongs to the SN54 series of logic integrated circuits, which are distinguished from commercial SN74 parts by their extended temperature ranges and stricter manufacturing tolerances. The JM38510 prefix indicates a specific military qualification standard managed by DLA Aerospace. This series is commonly used in avionics and defense electronics where long-term stability and radiation hardness are critical requirements.

Counter Dividers Replacement Considerations

Direct replacements include other SN54LS163 variants from qualified manufacturers. Verify pin compatibility and electrical characteristics before substitution. Generic SN74LS163 equivalents may not meet the temperature or reliability requirements.
