Counter Dividers datasheet and documents for SNJ54LS161AFK
Counter Dividers Overview
The SNJ54LS161AFK is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 20-lead LCCC package. The device functions as an up-counter with synchronous operation, featuring a maximum operating frequency of 22 MHz at nominal supply voltage. Key electrical characteristics include a load capacitance of 50 pF and a maximum output current of 0.02 A. The component is classified under the LS series logic family.
Counter Dividers Feature Summary
- Synchronous 4-bit binary counting capability with up-counting direction
- Military-grade operational reliability across extended temperature ranges
- High-speed performance suitable for demanding digital applications
Counter Dividers Applications
- Military aerospace electronic systems requiring robust logic components
- Industrial control equipment operating in extreme environmental conditions
- Test and measurement instrumentation utilizing high-reliability counters
Counter Dividers Procurement Notes
Verify the specific suffix AFK against official manufacturer documentation to confirm the exact package type and material specifications. Ensure that the procurement source provides traceability to the original manufacturer or authorized distributors. Confirm compliance with relevant export control classifications such as EAR99 before finalizing acquisition orders.
Counter Dividers Selection Notes
Select this component when designing systems that require synchronous 4-bit counting within harsh environmental constraints. The LS series offers established compatibility with standard TTL logic levels. Consider the 20-lead LCCC package for applications necessitating hermetic sealing or specific board space requirements compared to alternative DIP packages.
Counter Dividers Part Context
This part belongs to the SNJ54LS161 family of synchronous binary counters. It shares functional similarities with other variants like the SNJ54ALS161BJ but differs in speed and power consumption characteristics typical of the LS technology. The SNJ prefix indicates a military-grade qualification level distinct from commercial counterparts.
Counter Dividers Replacement Considerations
Potential substitutes include SNJ54ALS161BJ and SNJ54AS161J. Verify pinout compatibility and electrical parameter alignment, particularly regarding propagation delay and power dissipation, before implementing any cross-series replacements.
