MC74HC161AFEL

Counter Dividers Overview

The MC74HC161AFEL is a high-performance silicon-gate CMOS device from the 74HC series, functioning as a synchronous 4-bit binary counter with parallel load capability. It features asynchronous reset and operates within a voltage range of 2.0 to 6.0 V. The component supports an operating temperature range of -55°C to 125°C and utilizes a 16-SOIC surface-mount package. Designed for compatibility with standard CMOS outputs and LSTTL interfaces via pull-up resistors, it offers low input current and high noise immunity characteristics suitable for robust digital logic applications.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with parallel data loading functionality
• Asynchronous reset mechanism for immediate clearing of count states
• Wide operating voltage range supporting 2.0 V to 6.0 V supply rails
• High noise immunity and low input current typical of CMOS technology

Counter Dividers Applications

• Digital frequency division circuits
• Timing sequence generation systems
• Pulse width modulation signal processing
• General-purpose binary counting in industrial control equipment

Counter Dividers Procurement Notes

Verify the specific suffix AFEL against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and material composition requirements relevant to your manufacturing region. Confirm availability status as distribution channels may vary by region. Cross-reference the manufacturer part number with authorized distributors to prevent sourcing counterfeit components. Validate that the selected variant meets the thermal and electrical requirements of your target application environment.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with parallel load is required in harsh environments due to its extended temperature range. Consider the HC163 if a synchronous reset is preferred over the asynchronous reset provided here. Ensure the design accommodates the 2.0 V to 6.0 V operating voltage window. Verify interface compatibility with downstream logic families, noting that direct CMOS interfacing is supported while LSTTL compatibility requires pull-up resistors.

Counter Dividers Part Context

This device belongs to the 74HC family of high-speed CMOS logic integrated circuits manufactured by onsemi. It serves as a direct pin-compatible replacement for legacy LS161 devices, facilitating upgrades in existing designs. The 74HC series is characterized by wide voltage operation and compatibility with various logic families, making it a versatile choice for modern digital systems requiring reliable binary counting functions.

Counter Dividers Replacement Considerations

MC74HC161ADG: Pin-compatible alternative with similar electrical characteristics. MC74HC163A: Synchronous reset variant instead of asynchronous. MC74HC161A: Standard version without specific suffix variations.
