HCF4024BEY

Counter Dividers Overview

The HCF4024BEY is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, functioning as a 7-stage ripple-carry binary counter. It operates within a supply voltage range of 3 V to 20 V and supports an operating temperature from -55 °C to +125 °C. The device utilizes master-slave flip-flops for all stages and advances state on the negative transition of input pulses. Propagation delay times vary by stage and voltage; typical delays at 10 V are 80 ns for the first stage and 40 ns for subsequent stages. Maximum clock frequency reaches 16 MHz at 10 V.

Counter Dividers Feature Summary

• Features buffered inputs and outputs with standardized symmetrical characteristics.
• Provides fully static operation with Schmitt trigger action on the input pulse line.
• Includes a common reset input that resets the counter to the all-zeros state.
• Ensures unlimited clock rise and fall times due to input buffering.

Counter Dividers Applications

• Ripple-carry binary counting
• Frequency division
• Digital timing circuits

Counter Dividers Procurement Notes

Verify component authenticity through official STMicroelectronics channels or authorized distributors. Confirm package integrity upon receipt, as the DIP-14 housing may be susceptible to mechanical stress during transit. Ensure storage conditions align with manufacturer guidelines to prevent moisture damage prior to soldering.

Counter Dividers Selection Notes

Select this component when a 7-bit asynchronous binary counter is required for medium-speed applications. Verify that the system logic levels match the CMOS specifications across the intended operating voltage range. Consider the propagation delay characteristics relative to the maximum clock frequency requirements of the design.

Counter Dividers Part Context

This part belongs to the HCF4024B series, which includes variants such as the SOP package versions HCF4024BM1 and HCF4024M013TR. All members share identical functional logic but differ in physical packaging dimensions and mounting styles.
