SNJ54LS161AW

Counter Dividers Overview

The SNJ54LS161AW 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-pin ceramic dual in-line package (CDIP). The device functions as a positive-edge-triggered up-counter with synchronous parallel loading capabilities. Key electrical specifications include a maximum operating frequency of 30 MHz under nominal supply conditions and a load capacitance rating of 15 pF. The logic family is designated as LS, indicating Low-power Schottky TTL compatibility.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting operation with up-direction capability
• Positive-edge triggering mechanism for clock input synchronization
• Synchronous parallel data loading feature for preset values
• Extended industrial temperature range suitable for harsh environments

Counter Dividers Applications

• Digital timing sequences requiring precise synchronous control
• Frequency division circuits in communication systems
• Event counting applications in industrial instrumentation
• Address generation for memory decoding systems

Counter Dividers Procurement Notes

Verify the specific suffix 'AW' against official Texas Instruments documentation to confirm the exact package variant and material composition. Ensure that the procurement source provides traceability for military-grade or high-reliability ceramic packages. Confirm compliance with relevant export control classifications such as EAR99 before finalizing acquisition orders.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with low-power Schottky characteristics is required for high-temperature environments. Compare propagation delays and power dissipation against other LS series alternatives if speed or efficiency is critical. Ensure the system voltage aligns with standard TTL levels and verify pinout compatibility with existing PCB layouts.

Counter Dividers Part Context

This part belongs to the SN54LS161 series of synchronous 4-bit binary counters. The SNJ prefix typically denotes a military-grade or high-reliability version produced by Texas Instruments. The LS series indicates Low-power Schottky technology, offering a balance between speed and power consumption compared to standard TTL devices.

Counter Dividers Replacement Considerations

Compatible substitutes include SN54LS161AJ and SN54LS161AW from various manufacturers. Verify pin compatibility and electrical parameters before substitution.
