CD4045BPWR

Counter Dividers Overview

The CD4045BPWR is a CMOS frequency divider integrated circuit manufactured by Texas Instruments. It features a divide-by-1, 2, 3, or 4 counter section and a divide-by-2, 4, 8, or 16 counter section. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 10 MHz at 5 V. It utilizes a 16-lead Thin Shrink Small-Outline (TSSOP) package with a width of 4.4 mm.

Counter Dividers Feature Summary

• Integrates two independent frequency divider sections for flexible division ratios
• Supports multiple division configurations including divide-by-1 through divide-by-4 and divide-by-2 through divide-by-16
• Operates on standard CMOS logic levels with wide power supply tolerance

Counter Dividers Applications

• Frequency synthesis systems requiring precise clock division
• Digital clock generation circuits
• Timing control applications in consumer electronics

Counter Dividers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm that the operating environment remains within the specified temperature and voltage limits defined in the datasheet. Ensure ESD protection measures are implemented during handling due to the CMOS input structure characteristics.

Counter Dividers Selection Notes

Select this component when a single IC solution is required for both low-order and high-order frequency division stages. The TSSOP package offers a compact footprint suitable for space-constrained designs compared to traditional DIP packages. Verify that the required division ratios align with the available configuration options provided by the internal flip-flop architecture.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices produced by Texas Instruments. It serves as a specialized frequency divider distinct from general-purpose counters like the CD4017. The device is designed for applications requiring stable frequency reduction from a master clock source without external discrete components.
