Counter Dividers datasheet and documents for SNJ54290J
Counter Dividers Overview
The SNJ54290J is a TTL/H/L series asynchronous negative edge triggered 3-bit up decade counter housed in a CDIP14 ceramic DIP-14 package. Manufactured by Texas Instruments, this component functions as a decade counter and is part of the broader SN54290 family which includes 4-bit binary counters. It is designed for digital counting applications requiring asynchronous operation.
Counter Dividers Feature Summary
- Asynchronous negative edge triggering mechanism for decade counting operations
- Constructed with TTL/H/L series logic technology
- Encapsulated in a robust ceramic dual in-line package (CDIP14) suitable for high-reliability environments
Counter Dividers Applications
- Digital decade counting circuits
- Asynchronous frequency division systems
- Military or aerospace electronic assemblies requiring ceramic packaging
Counter Dividers Procurement Notes
Verify the specific suffix 'J' indicates the ceramic DIP-14 package variant when sourcing. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for current production status as legacy components may have limited availability. Ensure compatibility with existing TTL logic voltage levels in the target design.
Counter Dividers Selection Notes
Select this component when a 3-bit asynchronous decade counter is required within a military-grade or high-reliability specification. The ceramic package offers superior environmental resistance compared to plastic variants. Consider the SN54290 family datasheet for detailed electrical characteristics and timing parameters relevant to the entire series.
Counter Dividers Part Context
This device belongs to the SN54290 family of decade and 4-bit binary counters produced by Texas Instruments. The SNJ54290J specifically denotes the ceramic package version of the standard SN54290 logic IC. It serves as a fundamental building block for sequential logic circuits in industrial and defense electronics.
Counter Dividers Replacement Considerations
The SN54290 is the base model number. Verify if other manufacturers offer pin-compatible equivalents. Ensure any substitute maintains the same asynchronous triggering and decade counting functionality.
