74F160ASJX

Overview

The Fairchild Semiconductor 74F160ASJX is a synchronous presettable BCD decade counter featuring an asynchronous reset. It operates within the F/FAST logic series and is housed in a 16-SOIC package with a width of 5.30mm. The device functions as a 4-bit positive edge-triggered counter element. It supports synchronous preset capabilities for flexible counting applications while providing an asynchronous clear function to force the output to zero independently of the clock signal.

Feature Summary

• Synchronous presettable BCD decade counting functionality
• Asynchronous reset capability for immediate clearing
• Positive edge-triggered operation for precise timing control

Applications

• Digital frequency division circuits
• Timekeeping and digital clock modules
• Event counting systems

Procurement Notes

Verify RoHS compliance status carefully, as sources indicate non-compliance for this specific suffix variant. Confirm the manufacturer origin, noting potential distribution through Rochester Electronics or Fairchild. Ensure the 16-SOIC package dimensions match your PCB footprint requirements before ordering.

Selection Notes

Select this component when a synchronous BCD decade counter with asynchronous reset is required. It is suitable for designs needing modulo-10 counting behavior. Compare against the 74F161A for binary counting needs or the 74F163A for synchronous reset options. Ensure voltage levels align with system requirements.

Part Context

This part belongs to the 74F160 series of high-speed logic counters manufactured by Fairchild Semiconductor. It is closely related to the 74F161A (binary) and 74F163A (synchronous reset) variants. The 'ASJX' suffix denotes the specific SOIC package and tape-and-reel packaging configuration.

Replacement Considerations

Direct substitutes include the 74F160AN or other 74F160 variants in different packages. For binary counting, consider the 74F161ASJX. Verify pin compatibility and electrical characteristics before swapping.
