Overview
The Texas Instruments 5962-8952601LA is a synchronous 8-bit up/down counter, functionally equivalent to the SN54AS869. It operates within an extended temperature range of -55°C to 125°C and utilizes a 24-pin CDIP package. The device is currently in active production status. As a military-grade component under the MIL-STD-5962 qualification, it provides high-speed counting capabilities suitable for demanding industrial and aerospace applications requiring robust performance across wide thermal variations.
Feature Summary
- Synchronous 8-bit up/down counting architecture
- Extended industrial and military temperature operation
- High-speed AS logic family performance
Applications
- Aerospace digital systems
- Military instrumentation counters
- Industrial control logic
Procurement Notes
Verify the manufacturer source carefully, as this part number may be sourced from authorized distributors or qualified secondary suppliers. Confirm the specific marking code matches the SNJ54AS869JT designation to ensure authenticity. Request full traceability documentation and material compliance certificates prior to purchase to meet military procurement standards.
Selection Notes
Select this component when a synchronous 8-bit counter with AS-series speed is required for environments exceeding standard commercial temperature limits. Ensure the design supports the 24-pin CDIP footprint and voltage requirements associated with the SN54AS series. Validate that the application does not require asynchronous reset functionality unless explicitly supported by the specific variant datasheet.
Part Context
This part belongs to the Texas Instruments SN54AS family of advanced Schottky logic devices. The 5962 prefix indicates a military-grade version manufactured under strict quality controls. It serves as a direct replacement for other SN54AS869 variants, offering identical electrical characteristics but with enhanced reliability specifications for defense and space applications.
Replacement Considerations
Direct substitutes include other SN54AS869 variants with different suffixes indicating package or temperature grade changes. Verify pin compatibility and voltage levels before swapping. Cross-reference with SNJ54AS869JT markings to confirm functional equivalence.
