MC74AC160DR2

Counter Dividers Overview

The MC74AC160DR2 is a synchronous decade counter from the onsemi 74AC series, housed in a 16-pin SOIC package. It features a 4-bit binary count with a synchronous clear input and a ripple clock output for cascading. The device operates within a supply voltage range of 2 V to 6 V, supporting standard CMOS logic levels. Key electrical characteristics include a propagation delay of approximately 8.5 ns at 3.3 V and 6.5 ns at 5 V. It provides high noise immunity and low power consumption typical of AC logic families, suitable for general-purpose counting applications in industrial and consumer electronics.

Counter Dividers Feature Summary

• Synchronous four-bit decade counting with internal carry lookahead for high-speed operation
• Dedicated synchronous clear input allows immediate reset independent of the clock signal
• Ripple clock output facilitates easy cascading of multiple counters without external gating

Counter Dividers Applications

• Digital timing circuits requiring precise interval generation
• Frequency division networks in communication systems
• Event counting modules in industrial control panels

Counter Dividers Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required package style and tape/reel configuration for your assembly process. Cross-reference RoHS compliance status if environmental regulations apply to your final product deployment.

Counter Dividers Selection Notes

Select this component when a synchronous decade counter is preferred over asynchronous types for reduced glitching. Consider the 74AC series speed-power trade-off compared to 74HC or 74LVC alternatives based on system voltage and switching frequency requirements. Verify that the operating temperature range meets the environmental conditions of the intended application site.

Counter Dividers Part Context

This component belongs to the widely adopted 74AC logic family, known for faster switching speeds than standard 74LS counterparts while maintaining CMOS low power characteristics. The MC74AC160 specifically implements decade (mod-10) counting, distinguishing it from binary mod-16 variants like the MC74AC161. It serves as a fundamental building block for digital arithmetic and state machine implementations.

Counter Dividers FAQ

How does the synchronous clear function differ from asynchronous clear?

The synchronous clear input resets the counter outputs only on the active edge of the clock signal, ensuring clean state transitions. Asynchronous clear would reset immediately regardless of the clock phase.

What is the purpose of the ripple clock output?

The ripple clock output provides a pulse that indicates the completion of a count cycle, allowing multiple counters to be cascaded easily for higher modulus counting without additional logic gates.
