HEF4024BP,652

Counter Dividers Overview

The HEF4024BP,652 is a 7-stage binary ripple counter from the HEF4000B series. It features a clock input (CP) and an overriding asynchronous master reset (MR). The device advances on the HIGH to LOW transition of CP and includes seven fully buffered parallel outputs (Q0 to Q6). Each stage utilizes a static toggle flip-flop. Recommended operating conditions specify a supply voltage range of 3 V to 15 V. Propagation delays vary by voltage: at 5 V, tPHL for CP to Q0 ranges from 73 ns to 200 ns; at 15 V, it ranges from 17 ns to 50 ns.

Counter Dividers Feature Summary

• Tolerant of slow clock rise and fall times
• Fully static operation with standardized symmetrical output characteristics
• Asynchronous master reset overrides clock inputs

Counter Dividers Applications

• Frequency dividers
• Time delay circuits

Counter Dividers Procurement Notes

Verify the specific package variant against the datasheet ordering information. Confirm that the DIP14 plastic dual in-line package matches the required footprint dimensions. Ensure the component meets the specified ambient temperature range of -40 °C to +85 °C for the intended application environment.

Counter Dividers Selection Notes

Select this component when a 7-bit binary counting sequence is required without external decoding logic. The asynchronous master reset allows immediate clearing of all stages independent of the clock signal. Verify that the load capacitance requirements align with the dynamic propagation delay specifications provided in the datasheet tables.

Counter Dividers Part Context

Counter Dividers FAQ

How does the master reset function interact with the clock?

The master reset is asynchronous and overrides the clock input. A HIGH level on the MR pin clears all counter stages and forces all outputs LOW, regardless of the state of the clock.

What triggers the counter to advance?

The counter advances on the HIGH to LOW transition of the clock pulse (CP).
