HEF4024BT,653

Counter Dividers Overview

The HEF4024BT,653 is a 7-stage binary ripple counter from the HEF4000B logic family, manufactured by NXP Semiconductors. It features a clock input (CP) and an overriding asynchronous master reset input (MR). The device provides seven fully buffered parallel outputs (Q0 to Q6), advancing on the HIGH-to-LOW transition of the clock signal. It operates within a recommended supply voltage range of 3 V to 15 V referenced to ground. The component is housed in a SO14 plastic small outline package (SOT108-1) with 14 leads.

Counter Dividers Feature Summary

• Fully static operation tolerant of slow clock rise and fall times
• Overriding asynchronous master reset input clears all stages independently of the clock
• Seven fully buffered parallel outputs for direct reading of counter states
• Complies with JEDEC standard JESD 13-B

Counter Dividers Applications

• Frequency dividers
• Time delay circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the procurement channel sources genuine NXP Semiconductors products. Ensure the component meets the specified ambient temperature operating range of -40 °C to +85 °C for the intended application environment. Check for compliance with relevant material declarations.

Counter Dividers Selection Notes

Select this component when a 7-stage binary counting function is required within the HEF4000B logic family. Consider the SO14 surface-mount package for board space constraints. Evaluate the propagation delay characteristics against the system clock frequency requirements at the target supply voltage. Ensure unused inputs are properly terminated to VDD or VSS.

Counter Dividers Part Context

This part belongs to the HEF4000B series of CMOS logic devices produced by NXP Semiconductors. The 'BT' designation indicates the SO14 surface-mount package variant, while '653' is the specific reel packing code. It is distinct from through-hole DIP variants like the HEF4024BP.

Counter Dividers FAQ

How does the master reset input affect the counter?

A HIGH level on the MR input clears all counter stages and forces all outputs LOW, independent of the clock signal.

What triggers the counter to advance?

The counter advances on the HIGH-to-LOW transition of the clock pulse applied to the CP input.
