74LS162APC

Counter Dividers Overview

The 74LS162APC is a synchronous, presettable 4-bit binary decade counter manufactured by National Semiconductor. It operates on a positive-edge triggered clock signal and features synchronous parallel loading capabilities. The device functions as a decade counter, counting from zero to nine before resetting. It includes dedicated inputs for clear, load, and enable functions to control counting operations precisely. The component is designed for use in digital logic circuits requiring reliable sequential counting with synchronous data handling.

Counter Dividers Feature Summary

• Synchronous parallel loading of data inputs
• Positive-edge triggered clock operation
• Decade counting sequence (0-9)
• Dedicated synchronous clear and load controls

Counter Dividers Applications

• Digital frequency dividers
• Sequential control logic systems
• Time base generators
• Presettable counting circuits

Counter Dividers Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the package type matches system requirements. Check RoHS compliance status if environmental regulations apply. Ensure the suffix 'PC' corresponds to the specific package variant needed for your PCB layout. Validate pin compatibility with existing designs.

Counter Dividers Selection Notes

Select this component when synchronous presettable decade counting is required. It is suitable for applications needing precise timing sequences controlled by a clock signal. Consider the LS logic family characteristics for speed and power consumption. Verify voltage levels match the system supply. Evaluate pinout compatibility if replacing older components.

Counter Dividers Part Context

This part belongs to the 74LS series of logic integrated circuits. National Semiconductor was a major producer of such components before being acquired by Texas Instruments. The 74LS162 is a standard synchronous decade counter within this lineage. It shares functional similarities with other 74xx series counters but offers specific synchronous loading features.

Counter Dividers Replacement Considerations

Check for equivalents like SN54LS162 or compatible variants from other manufacturers. Ensure logical function and pinout compatibility. Verify electrical specifications match the original design requirements. Confirm package dimensions fit the existing footprint.
