M38510/31508BEA

Counter Dividers Overview

The M38510/31508BEA is a synchronous 4-bit up/down counter manufactured by Texas Instruments. It features dual clock inputs for independent count direction control and an asynchronous clear function. The device operates within a temperature range of -55°C to 125°C and utilizes a 16-pin ceramic dual in-line package (CDIP).

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting capability with independent up and down clock inputs.
• Asynchronous master reset input for immediate clearing of all counter outputs.
• Ceramic dual in-line packaging designed for high-reliability military and aerospace applications.

Counter Dividers Applications

• Military digital signal processing systems requiring radiation-hardened or high-temperature logic components.
• Aerospace navigation and telemetry equipment operating in extreme thermal environments.
• High-reliability industrial control systems utilizing MIL-M-38510 qualified microcircuits.

Counter Dividers Procurement Notes

Verify the specific revision level and qualification class against current procurement specifications. Confirm that the CDIP package variant matches the required footprint and lead finish for the target assembly process. Ensure compliance with applicable defense standards and material declarations prior to final acquisition.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with separate up/down clocks is required for harsh environment operation. The LS series offers low power dissipation suitable for battery-operated or thermally constrained military platforms. Verify compatibility with existing TTL logic levels and system timing requirements before integration.

Counter Dividers Part Context

This part belongs to the SN54LS193 family of synchronous counters, specifically the military-grade variant under the JM38510 specification. It provides a robust solution for complex sequencing tasks where standard commercial parts lack sufficient environmental tolerance or reliability assurance for critical defense applications.
