Product Summary

The HEF4522BP is a synchronous programmable 4-bit BCD down counter with an active HIGH and an active LOW clock input, an asynchronous parallel load input, (PL), four parallel inputs (P0 to P3), a cascade feedback input (CF), four buffered parallel outputs, a terminal count output (TC) and an overriding asynchronous master reset input (MR). The HEF4522BP is a programmable, cascadable down counter with a decoded TC output for divide-by-n applications.
