Overview
The SNJ95161BJ is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within an extended temperature range of -55°C to 125°C and utilizes a 16-lead ceramic dual in-line package (CDIP). The device functions as a binary counter with an up-counting direction and includes load/preset input capabilities. It features a TCO output and supports a maximum frequency of 65 MHz at nominal supply voltage, with a load capacitance of 50 pF.
Feature Summary
- Synchronous 4-bit binary counting operation
- Extended industrial temperature range capability
- Ceramic dual in-line packaging for durability
Applications
- Military aerospace systems requiring high reliability
- Industrial control logic circuits
- Harsh environment data processing units
Procurement Notes
Verify the specific suffix 'BJ' against official Texas Instruments documentation to confirm exact pinout and electrical characteristics. Ensure compatibility with existing CDIP footprints and thermal management requirements for the -55°C to 125°C operating range before integration into final designs.
Selection Notes
Select this component when military-grade environmental tolerance and synchronous 4-bit counting are required. The ceramic package offers superior protection compared to plastic variants. Confirm that the 65 MHz maximum frequency meets system timing constraints and that the 16-pin CDIP form factor fits the mechanical design.
Part Context
This part belongs to the AS/ALS series of synchronous counters from Texas Instruments. It provides reliable binary counting functionality for digital logic applications. The SNJ prefix indicates a military-grade qualification level, ensuring performance under extreme conditions where standard commercial parts may fail.
Replacement Considerations
Check for direct equivalents such as SNJ54AS161J or SNJ54ALS161J if pin-compatible alternatives are needed. Verify that any substitute maintains the same synchronous operation, CDIP package, and extended temperature specifications.
