描述 Description

This device divides the incoming clock frequency by a number (a power of 2) that is preset by the Programming inputs. It has two Clock inputs, either of which may be used as a clock inhibit. The device also has an active-low Reset, which initializes the internal flip-flop states. Test Point outputs (TP1, TP2, TP3) are provided with HD74HC292 to facilitate incoming inspections.

Test Point output is provided with HD74HC294 to facilitate incoming inspections.
