SN54LS93J

Counter Dividers Overview

The SN54LS93J is a hermetically sealed, military-grade binary counter from the LS logic series. It features a 14-pin Ceramic Dual In-line Package (CDIP) and operates within an extended temperature range of -55°C to +125°C. The device functions as a divide-by-two and divide-by-eight counter, providing four asynchronous toggle outputs.

Counter Dividers Feature Summary

• Provides independent divide-by-two and divide-by-eight counting stages
• Features hermetic ceramic packaging for environmental protection
• Supports operation across the full military temperature range

Counter Dividers Applications

• Military defense systems requiring radiation-hardened or high-reliability components
• Avionics timing and frequency division circuits
• Spacecraft telemetry and command logic counters

Counter Dividers Procurement Notes

Verify that the specific orderable part number matches the required package variant, such as CDIP or CFP, as availability varies by configuration. Confirm RoHS exemption status and lead finish specifications directly with Texas Instruments or authorized distributors, as these details are critical for military procurement compliance and soldering processes.

Counter Dividers Selection Notes

Select this component when a hermetically sealed, military-qualified binary counter is required. Ensure the design accommodates the asynchronous nature of the LS series toggles. Verify that the 14-pin CDIP footprint aligns with the target printed circuit board layout and that the operating voltage remains within standard TTL limits.

Counter Dividers Part Context

This device belongs to the SN54LS90/92/93 family of decade, divide-by-twelve, and binary counters manufactured by Texas Instruments. The 'SN' prefix indicates commercial/military grade, while '54' denotes the extended temperature range. The 'LS' suffix identifies Low-power Schottky logic technology, offering improved power dissipation characteristics compared to standard TTL.

Counter Dividers Replacement Considerations

Compatible substitutes include SN54LS90J and SN54LS92J. Cross-reference pinouts and electrical specifications before implementation.
