CD40161BPW

Counter Dividers Overview

The CD40161BPW is a synchronous programmable 4-bit binary counter manufactured by Texas Instruments. It belongs to the 4000/14000/40161 series and utilizes CMOS technology. The device features an asynchronous clear input, a synchronous parallel load capability, and a ripple clock output (TCO). It operates in a positive counting direction with a maximum frequency of 2 MHz at nominal supply voltage. The component is housed in a 16-pin TSSOP package with a lead pitch of 0.25 mm.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting operation with up-counting direction
• Asynchronous master reset for immediate clearing of all outputs
• Synchronous parallel data loading for preset value initialization
• Ripple clock output providing carry propagation signal

Counter Dividers Applications

• Digital timing sequences and event counters
• Frequency division circuits
• Programmable digital control logic systems

Counter Dividers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 surface mount package variant. Ensure the order matches the required lead pitch and thermal characteristics. Confirm RoHS compliance status as per current manufacturer documentation. Validate that the asynchronous clear and synchronous load functions align with the target circuit design requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a compact surface mount solution for synchronous binary counting is required. The TSSOP-16 package offers space efficiency compared to through-hole alternatives. Consider the 2 MHz operating limit for high-speed applications. Verify compatibility with standard CMOS logic levels and power supply ranges suitable for the intended system environment.

Counter Dividers Part Context

This part is a member of the Texas Instruments 4000B series of CMOS logic devices. It serves as a fundamental building block for sequential logic designs. The BPW designation specifically identifies the plastic small-outline package variant within the broader CD40161 family. It complements other logic gates for complex digital system implementations.
