MC14526 presettable 4-bit binary down counter

The MC14526 presettable 4-bit binary down counter is a digital logic component designed to count downward in binary from a preset value. As a presettable counter, it allows an initial 4-bit value to be loaded and then decremented by clock pulses, making it suitable for use in timing sequences, event counting, digital control logic, and other general-purpose counting applications.

This component is commonly integrated into larger digital systems where a controlled down-count sequence is required. Typical usage patterns include loading a starting count, gating or enabling the counting operation, and detecting terminal count conditions for cascade or reset actions. Because it is a 4-bit device, it represents counts in binary from 0 to 15 and can be cascaded with other counters or logic to form wider counting ranges.

The MC14526 is intended for designers, engineers, and hobbyists working on prototype or production projects that require a straightforward presettable down-counter building block. When selecting this device for a design, review the manufacturer's datasheet and recommended application notes for electrical characteristics, timing, recommended operating conditions, and available package options to ensure compatibility with your system requirements.
