74LVC163DB,112

Counter Dividers Overview

The Nexperia 74LVC163DB,112 is a synchronous presettable 4-bit binary counter housed in a 16-lead SO plastic small outline package (SOT109-1). It operates on a positive-going clock edge and features an internal look-ahead carry for high-speed serial cascading. The device supports parallel loading via the PE input and includes a synchronous master reset (MR) that clears outputs to LOW upon the next clock transition. Supply voltage ranges from 1.2 V to 3.6 V, with inputs tolerant up to 5.5 V.

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking
• Internal look-ahead carry simplifies serial cascading
• Parallel load capability controlled by active LOW enable input
• Synchronous master reset clears all outputs on clock edge

Counter Dividers Applications

• High-speed counting applications
• Serial cascaded counter systems
• Digital timing circuits requiring precise synchronization

Counter Dividers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the standard tape-and-reel packaging configuration as defined in the official datasheet. Confirm the package type matches the SOT109-1 specification for the 'D' variant. Ensure the procurement channel provides traceability to the manufacturer's production records to guarantee component authenticity and compliance with RoHS directives.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load functionality is required. The internal look-ahead carry feature makes it suitable for designs needing efficient multi-stage cascading without external logic gates. Verify that the operating voltage range of 1.2 V to 3.6 V aligns with the system power supply and that the 5.5 V input tolerance accommodates interfacing with higher voltage logic levels.

Counter Dividers Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. The 74LVC163 specifically addresses the need for synchronous counters with preset capabilities. It complements other logic families by offering high-speed performance at reduced supply voltages while maintaining compatibility with standard TTL interface levels.

Counter Dividers Replacement Considerations

Check for alternative packages such as TSSOP16 or DHVQFN16 if footprint changes are acceptable. Verify functional equivalence with other 74LVC163 variants from different manufacturers, ensuring pinout compatibility and identical electrical characteristics for direct substitution.
