CD40161BPWE4

Counter Dividers Overview

The CD40161BPWE4 is a synchronous four-bit binary counter manufactured by Texas Instruments. It operates within the 4000/14000/40000 series and utilizes CMOS technology. The device features an up-counting direction and includes load/preset inputs for programmable functionality. It is housed in a 16-lead TSSOP package with a width of 0.25 inches. The component supports a maximum operating frequency of 2 MHz at nominal supply voltage and has a load capacitance rating of 50 pF.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting operation
• Programmable preset capability via dedicated inputs
• Up-counting direction logic
• CMOS construction for low power consumption

Counter Dividers Applications

• Digital timing circuits requiring precise count sequences
• Frequency division networks in signal processing systems

Counter Dividers Procurement Notes

Verify the specific suffix E4 to confirm compliance with environmental standards such as RoHS. Ensure the TSSOP-16 package dimensions match the target PCB footprint requirements. Confirm that the synchronous nature of the counter aligns with the system clock distribution strategy to prevent race conditions during state transitions.

Counter Dividers Selection Notes

Select this component when a synchronous four-bit counter with parallel load capability is required. The CMOS technology offers advantages in low static power consumption compared to bipolar alternatives. Consider the 2 MHz frequency limit when designing high-speed digital systems. The TSSOP package is suitable for surface-mount assembly processes.

Counter Dividers Part Context

This part belongs to the CD40161 family of synchronous binary counters. The BPW designation indicates the plastic TSSOP package variant, while the E4 suffix typically denotes lead-free and RoHS-compliant manufacturing. It serves as a fundamental building block for sequential logic designs within the broader 4000-series CMOS logic ecosystem.

Counter Dividers Replacement Considerations

CD40161BPWR is a reel-packaged equivalent from Texas Instruments. CD40161BE is a DIP-package alternative from RCA. Verify pin compatibility and electrical specifications before substituting.
