74VHC163SJX

Counter Dividers Overview

The onsemi 74VHC163SJX is a 4-bit binary counter with synchronous clear, fabricated using advanced high-speed CMOS technology. It operates within a supply voltage range of 2.0V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device features a maximum clock frequency (fMAX) of 185 MHz at VCC = 5V and includes two count enable inputs plus a terminal count output for versatile cascading. It utilizes D-type edge-triggered flip-flops with parallel data inputs and outputs active on the rising edge of the clock pulse.

Counter Dividers Feature Summary

• Synchronous counting and loading capabilities with dedicated reset and parallel enable functions.
• High-speed synchronous expansion through terminal count output and dual count enable inputs.
• Power down protection provided on all inputs to prevent device destruction during mismatched supply voltages.

Counter Dividers Applications

• Programmable frequency dividers
• Multistage counter implementations
• Digital timing circuits

Counter Dividers Procurement Notes

Verify that the ordering code suffix 'X' corresponds to the Tape and Reel packaging format as specified in the datasheet. Confirm the package type matches the required surface mount footprint, specifically the 16-Lead Small Outline Package (SOP). Ensure compatibility with the intended logic family voltage levels before integration into the final design.

Counter Dividers Selection Notes

Select this component when a high-speed synchronous modulo-16 binary counter is required. It is suitable for applications needing interface between 5V and 3V systems due to its input protection circuitry. Consider the 185 MHz typical maximum frequency for high-speed digital designs requiring low power dissipation and noise immunity.

Counter Dividers Part Context

This part belongs to the 74VHC series of advanced high-speed CMOS logic devices. It is functionally compatible with the 74HC163 but offers improved speed performance. The device is manufactured by Fairchild Semiconductor, which has since become part of onsemi, maintaining the same pinout and logical operations as the standard 74HC163 counterpart.

Counter Dividers Replacement Considerations

SN74LV163ANSR from Texas Instruments is a confirmed substitute part number available in the market.
