SN74AS161D

Counter Dividers Overview

The SN74AS161D is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. The device utilizes the AS logic series and features a 16-SOIC surface-mount package. It counts in an upward direction with positive-edge triggering.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting operation
• Positive-edge triggered clock input
• Upward counting sequence

Counter Dividers Applications

• Digital frequency division circuits
• Binary timing sequences
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics also lists this part number. Confirm that the SOIC-16 package matches the design requirements. Ensure the AS logic family characteristics align with the system's speed and power constraints before finalizing procurement.

Counter Dividers Selection Notes

Select this component for applications requiring synchronous 4-bit binary counting with high-speed performance typical of the AS logic family. Consider the 16-SOIC package for surface-mount assembly needs. Verify compatibility with standard 5V logic levels and ensure the operating temperature range meets environmental specifications.

Counter Dividers Part Context

This component belongs to the SN74AS161 series of synchronous counters. It shares functional similarities with other 4-bit binary counters like the SN74LS161 but offers different speed and power characteristics due to its AS logic construction. It is distinct from decade counters such as the SN74AS160.
