CD74HCT161E

Counter Dividers Overview

The CD74HCT161E is a high-speed CMOS logic device functioning as a 4-bit binary synchronous counter. It features an asynchronous reset input and operates within a supply voltage range of 2 V to 6 V. The component supports up-counting sequences and includes synchronous parallel load capabilities. It is housed in a 16-pin PDIP package and is rated for operation across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive edge triggering
• Asynchronous master reset function for immediate clearing
• Synchronous parallel data loading capability
• High-speed CMOS technology compatible with HCT logic standards

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation
• Digital clock counters

Counter Dividers Procurement Notes

Verify the specific suffix 'E' corresponds to the 16-pin PDIP package configuration. Confirm RoHS compliance status through official manufacturer documentation, as historical batches may vary. Ensure the operating environment remains within the specified -55 °C to +125 °C temperature limits to maintain guaranteed performance parameters.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with asynchronous reset is required in a through-hole design. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS power advantages. Consider alternative packages like SOIC if surface-mount assembly is necessary for the target application.

Counter Dividers Part Context

This device belongs to the Texas Instruments CD74HCT161 family of high-speed CMOS logic counters. It shares functional similarities with other 4-bit binary counters but is distinguished by its specific HCT input compatibility and asynchronous reset feature. The part is designed for general-purpose digital counting applications requiring reliable synchronous operation.

Counter Dividers Replacement Considerations

CD74HC161E: Similar functionality with HC series inputs. SN74HCT161N: Equivalent function from National Semiconductor/TI lineage.
