HEF4520BP Description

Short technical summary and product information.

The HEF4520BP is a dual 4-bit internally synchronous binary counter. It offers flexibility with an active HIGH clock input (CP0) and an active LOW clock input (CP1), both of which can also function as clock enable inputs. The counter includes an active HIGH overriding asynchronous master reset input (MR) that resets all counter outputs to LOW, independent of the clock inputs.

 

Schmitt-trigger action is incorporated into the clock input circuitry, making the HEF4520BP highly tolerant to slower clock rise and fall times. This integrated circuit is suitable for various digital counting applications where reliable synchronous operation and noise immunity are required.

 

This component is available in a 16-lead Dual In-line Package (DIP) with a standard 0.300-inch (7.62mm) lead spacing, designed for through-hole mounting.
