CD74AC161E

Counter Dividers Overview

The CD74AC161E is a synchronous binary counter from the AC logic series, manufactured by Harris Corporation. It features a 4-bit up-counting architecture with positive edge triggering and includes asynchronous reset functionality. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports a maximum operating temperature of 125 °C. It is housed in a 16-pin PDIP package designed for through-hole mounting.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive edge triggering
• Asynchronous reset capability for immediate state clearing
• Wide operational voltage range supporting low-power applications

Counter Dividers Applications

• Digital timing sequences
• Frequency division circuits
• Event counting systems

Counter Dividers Procurement Notes

Verify manufacturer origin as Harris Corporation rather than Texas Instruments. Confirm RoHS compliance status due to conflicting documentation. Ensure the PDIP-16 through-hole package matches design requirements. Validate electrical specifications against the specific Harris datasheet version.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous binary counting with an asynchronous reset function. The AC series offers a balance of speed and power consumption suitable for general-purpose digital logic. Verify that the 1.5 V to 5.5 V supply range aligns with the system power rails.

Counter Dividers Part Context

This part belongs to the CD74AC161 family of synchronous binary counters. While similar parts exist from other manufacturers like Texas Instruments, the Harris Corporation variant may exhibit distinct electrical characteristics or pinout configurations. Always reference the specific Harris datasheet for accurate implementation details.
