CD4029BPWR

Counter Dividers Overview

The CD4029BPWR is a CMOS presettable up/down counter from the Texas Instruments CD4000B series. It features a 4-bit binary or decade counting capability with synchronous operation and positive-edge triggering. The device supports both up and down counting directions and includes an asynchronous reset function. It operates within a supply voltage range of 3 V to 18 V and functions reliably across an extended temperature range of -55 °C to +125 °C. The component is housed in a 16-pin TSSOP surface-mount package.

Counter Dividers Feature Summary

• Supports selectable binary or decade counting modes for flexible digital sequencing applications
• Enables bidirectional counting through dedicated up/down control inputs
• Provides tri-state outputs for direct interfacing with bus systems

Counter Dividers Applications

• Digital frequency dividers and prescalers
• Time-base generators and real-time clocks
• Position counters in industrial automation

Counter Dividers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status as indicated in official datasheets, noting that manufacturing sites may vary. Ensure the operating environment remains within the specified -55 °C to +125 °C thermal limits to maintain signal integrity and prevent latch-up conditions during high-voltage transients.

Counter Dividers Selection Notes

Select this component for designs requiring low-power CMOS logic with wide voltage tolerance. It serves as a suitable alternative to standard TTL counters in battery-operated systems due to its broad 3 V to 18 V supply range. Consider the TSSOP footprint constraints and ensure adequate thermal management if operating near the upper temperature extremes.

Counter Dividers Part Context

This part belongs to the CD4000B family of CMOS logic devices, known for high noise immunity and low power consumption. The CD4029B specifically addresses applications needing programmable counting sequences. The 'PWR' designation indicates a plastic small-outline package optimized for automated surface-mount assembly processes.
