DESCRIPTION
HCF40103B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages.
HCF40103B consists of an 8-stage synchronous down counter with a single output that is active when the internal count is zero. This device contains a single 8-bit binary counter. It has control inputs for enabling or disabling the clock, for clearing the counter to its maximum count, and for presetting the counter either synchronously or asynchronously.
