HCF4029BEY

Counter Dividers Overview

The HCF4029BEY is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP-16 packages. It functions as a four-stage binary or BCD-decade up/down counter with look-ahead carry provisions. The device features a single clock input, carry-in (clock enable), binary/decade select, up/down control, preset enable, and four individual jam signals. Outputs include Q1 through Q4 and a carry-out signal. It supports parallel clocking for synchronous high-speed response or ripple clocking for slower clock inputs.

Counter Dividers Feature Summary

• Supports both binary and BCD-decade counting modes with selectable up or down direction
• Includes asynchronous preset capability via dedicated jam inputs and preset enable signal
• Enables multi-package synchronization through parallel or ripple clocking configurations
• Provides look-ahead carry functionality in both counting modes

Counter Dividers Applications

• Synchronous high-speed output response systems using parallel clocking
• Applications requiring slow clock input rise and fall times utilizing ripple clocking
• Digital counters requiring asynchronous state presetting via jam inputs
• Systems needing decade or binary counting with look-ahead carry propagation

Counter Dividers Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm package type and tape-and-reel availability. Confirm that the component meets JEDEC JESD13B standards for B series CMOS devices if required by your design specifications. Ensure compatibility with the specified operating temperature range and supply voltage limits before integration.

Counter Dividers Selection Notes

Select this component when a four-stage up/down counter with both binary and decade modes is required. It is suitable for designs needing asynchronous preset functionality via jam inputs. Consider its medium-speed operation characteristics and symmetrical output drive capabilities. Verify that the DIP-16 package fits the board layout constraints and that the power supply range aligns with system requirements.

Counter Dividers Part Context

The HCF4029B belongs to the HCF4000B series of high-density CMOS logic devices manufactured by STMicroelectronics. This series is designed to meet JEDEC JESD13B standards for B series CMOS devices. The HCF4029B specifically provides versatile counting capabilities within a compact integrated circuit form factor, suitable for various digital logic applications requiring reliable performance across wide temperature ranges.

Counter Dividers Replacement Considerations

Check for other members of the HCF4029B family or compatible four-stage up/down counters from STMicroelectronics. Verify pinout and functional equivalence before substitution. Ensure any replacement part supports the same binary/decade modes and asynchronous preset features.
