SN74HC161PW

Counter Dividers Overview

The SN74HC161PW is a synchronous 4-bit binary counter manufactured by Texas Instruments in the HC logic family. It features an asynchronous reset and operates on a positive-edge clock trigger. The device supports parallel data loading and includes ripple clock outputs for cascading applications. It functions within a supply voltage range of 2V to 6V and operates across a temperature range of -40°C to +85°C. The component is housed in a 16-pin TSSOP package.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with parallel load capability
• Asynchronous reset function for immediate clearing
• Positive-edge triggered clock input
• Ripple clock outputs for multi-stage expansion

Counter Dividers Applications

• Digital frequency division circuits
• Sequential pulse generation systems
• Cascaded timing control modules

Counter Dividers Procurement Notes

Verify that the specific part number SN74HC161PW corresponds to the Texas Instruments manufacturer, as Nexperia also produces the 74HC161PW variant. Confirm the package type is TSSOP-16 and check for RoHS compliance status. Ensure the operating voltage and temperature ranges match the design requirements before procurement.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load functionality is required. It is suitable for designs needing precise timing control via a clock signal. Consider the TSSOP package constraints and the 2V to 6V supply voltage range during circuit planning.

Counter Dividers Part Context

This component belongs to the SN74HC161 series of synchronous binary counters. It is part of the broader 74HC logic family, designed for high-speed digital applications. The device provides reliable counting operations with standard CMOS characteristics, making it a common choice for general-purpose digital logic designs.

Counter Dividers Replacement Considerations

The SN74HC161N serves as a pin-compatible alternative in a DIP-16 package. Other variants such as SN74HC161D or SN74HC161DBR offer similar functionality in different surface-mount packages.
