SN74HC161DT

Counter Dividers Overview

The SN74HC161DT is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2.0V to 6.0V and supports clock frequencies up to 35 MHz in the SOIC-16 package. The device features asynchronous reset, parallel data loading capabilities, and ripple clock outputs. It functions as an up-counter with a maximum operating temperature of 85°C and a minimum of -40°C.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting with positive-edge triggering
• Asynchronous master reset input for immediate zeroing
• Parallel data loading capability via dedicated inputs
• Ripple clock output for cascading multiple counters

Counter Dividers Applications

• Digital timing sequences and pulse generation circuits
• Frequency division and digital clock systems
• Event counting in industrial control logic
• Address generation for memory or I/O devices

Counter Dividers Procurement Notes

Verify the specific suffix 'DT' corresponds to the SOIC-16 surface-mount package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the selected component matches the required operating temperature range and voltage specifications for the target application environment.

Counter Dividers Selection Notes

Select this component for applications requiring synchronous 4-bit counting with low power consumption typical of HC logic families. Compare against LS or AS variants if higher speed or different drive strengths are needed. Ensure the PCB layout accommodates the SOIC-16 footprint and that the system voltage remains within the 2V to 6V operational window for reliable performance.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other industry-standard 4-bit synchronous counters but offers specific TI manufacturing quality standards. The SN74HC161 family provides a balance of speed and power efficiency suitable for general-purpose digital logic applications.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74HC161DR (tape and reel version) or equivalent parts from other manufacturers like ON Semiconductor or NXP, ensuring voltage and speed parameters match.
