The HEF4520BP is a dual 4-bit internally synchronous binary counter manufactured by NXP Semiconductors. This MSI (Medium Scale Integration) component offers flexibility with both active HIGH (CP0) and active LOW (CP1) clock inputs, allowing one to be used as a clock enable. It also includes an active HIGH overriding asynchronous master reset (MR) input.
The counter advances on either a LOW to HIGH transition of CP0 when CP1 is HIGH, or a HIGH to LOW transition of CP1 when CP0 is LOW. A HIGH signal on the MR input resets the counter outputs (O0 to O3) to LOW, irrespective of the clock inputs. The circuit's clock inputs incorporate Schmitt-trigger action, providing high tolerance to slower clock rise and fall times, making it suitable for various digital logic applications.
Available in a 16-lead plastic dual in-line package (DIL), the HEF4520BP is designed for through-hole mounting. Its synchronous operation and reset capability make it a versatile component for counting and timing circuits in digital systems.
