74LVC163BQ,115

Counter Dividers Overview

The Nexperia 74LVC163BQ,115 is a synchronous presettable 4-bit binary counter housed in a DHVQFN16 (SOT763-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant up to 5.5 V. The device includes internal look-ahead carry for high-speed cascading, synchronous reset via the MR pin, and parallel loading capabilities. It supports JEDEC standards for various voltage levels and provides ESD protection exceeding 2000 V (HBM).

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking on the positive-going edge.
• Internal look-ahead carry simplifies serial cascading of multiple counters.
• Synchronous master reset allows modification of maximum count using external logic.
• Parallel enable input facilitates direct data loading into the counter.

Counter Dividers Applications

• High-speed counting applications requiring precise timing synchronization.
• Digital systems utilizing serial cascading for extended bit-counting ranges.
• Mixed voltage environments requiring translation between 3.3 V and 5 V devices.

Counter Dividers Selection Notes

Select this component when a compact surface-mount solution is required for 4-bit synchronous counting. The DHVQFN16 package offers space efficiency compared to traditional SO or TSSOP variants. Ensure the design accommodates the 1.2 V to 3.6 V supply range and utilizes the synchronous reset feature for reliable state initialization without asynchronous glitches.

Counter Dividers Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Nexperia. The 'BQ' suffix specifically denotes the DHVQFN16 leadless package variant, distinguishing it from the standard SO16 (D) or TSSOP16 (PW) packages available in the same logical family. It shares functional compatibility with other 74LVC163 derivatives while offering distinct thermal and footprint characteristics.

Counter Dividers Replacement Considerations

Direct physical replacements include the 74LVC163D (SO16) and 74LVC163PW (TSSOP16), provided PCB layout adjustments are made for different package footprints. Functional equivalents from other manufacturers must be verified against the synchronous reset and look-ahead carry specifications.
