CD4059AD3

Counter Dividers Overview

The CD4059AD3 is a CMOS programmable divide-by-N counter manufactured by Texas Instruments. It operates within an extended temperature range of -55°C to 125°C and utilizes a 24-pin SBCDIP package. The device functions as a single 5-bit decade down counter with push-pull outputs and standard CMOS inputs. It supports bidirectional counting and includes Schmitt trigger inputs on the clock line for noise immunity.

Counter Dividers Feature Summary

• Programmable divide-by-N functionality supporting multiple modes of operation
• Bidirectional counting capability with dedicated up/down control
• Schmitt trigger clock input for improved signal integrity

Counter Dividers Applications

• Frequency division circuits
• Digital timing systems
• Programmable counters

Counter Dividers Procurement Notes

Verify the specific suffix 'AD3' corresponds to the 24-pin SBCDIP tube packaging configuration. Confirm the operating temperature range meets system requirements, as this variant supports industrial/extreme conditions. Ensure compatibility with standard CMOS logic levels for interfacing. Check for preproduction status if applicable, though current data indicates release.

Counter Dividers Selection Notes

Select this component when a programmable decade divider is required in harsh thermal environments. The bidirectional feature allows flexible count direction control. Verify that the 24-pin through-hole package fits the PCB layout constraints. Ensure the application does not exceed the specified maximum count rate of 6 MHz at the given supply voltage.

Counter Dividers Part Context

This part belongs to the CD4059 family of CMOS programmable counters. It serves as a digital building block for creating variable frequency dividers. The AD3 designation specifies the physical package and environmental rating compared to other variants in the series.

Counter Dividers Replacement Considerations

HEF4059BPB is a documented alternative offering similar programmable divide-by-N functionality. Verify pinout compatibility and electrical specifications before substitution.
