74VHC163FT

Counter Dividers Overview

The Toshiba 74VHC163FT is a synchronous presettable 4-bit binary counter fabricated with silicon gate C2MOS technology. It features a synchronous clear function and operates on the rising edge of the clock input. The device supports a supply voltage range of 2.0 V to 5.5 V and includes two enable inputs (ENP and ENT) alongside a carry output for cascading. It provides power-down protection on all inputs and ensures high noise immunity.

Counter Dividers Feature Summary

• Synchronous presettable 4-bit binary counting capability
• Synchronous clear function controlled by the clock signal
• High-speed operation with balanced propagation delays
• Power-down protection provided on all input pins

Counter Dividers Applications

• Implementation of n-bit counters through easy cascading
• Interface between 5 V and 3 V systems
• Two-supply systems such as battery backup applications

Counter Dividers Procurement Notes

Verify that the specific part number matches the synchronous clear variant, distinct from asynchronous versions in the same series. Confirm AEC-Q100 compliance requirements if automotive reliability standards are necessary for the application. Ensure the TSSOP16B package dimensions align with the PCB footprint design constraints.

Counter Dividers Selection Notes

Select this component when a synchronous clear mechanism is required for precise timing control relative to the clock edge. Consider the wide operating voltage range for flexibility in mixed-voltage environments. Evaluate the maximum clock frequency specifications against the system's timing requirements to ensure reliable operation across the full temperature range.

Counter Dividers Part Context

This device belongs to the 74VHC series of advanced high-speed CMOS logic integrated circuits. It is pin and function compatible with other standard 74 series logic types such as AC, HC, AHC, and LV variants. The 74VHC163FT specifically differs from the 74VHC161FT by utilizing a synchronous clear rather than an asynchronous one.

Counter Dividers Replacement Considerations

The 74VHC161FT is a related component within the same family but utilizes an asynchronous clear function instead of synchronous clearing. Verify functional compatibility regarding clear timing before substitution.
