CD74HCT4024E – HARRIS

Overview

The Texas Instruments CD74HCT4024E is a high-speed 7-bit asynchronous binary counter designed for digital signal processing and control applications. Its core functionality lies in its ability to reliably increment its internal state on each negative edge of the clock input, offering a predictable sequence of 2^7 possible outputs. A critical design consideration when utilizing this device is managing the inherent propagation delay from clock input to output change, which, while minimized in the HCT family, can still impact precise timing in high-frequency synchronous systems if not accounted for in the overall system architecture.

Key Features

• 7-bit asynchronous binary counter
• Maximum count rate: 25 MHz
• Operating voltage range: 4.5 V to 5.5 V
• Asynchronous reset capability
