Description:

1/2 Duty VFD Digital Clock

Features

* VFD display 24 hour clock function
* Directly drive VFD panels at 1/2 Duty cycle
* 4.194304MHz crystal oscillation
* Zero adjust function
* Integrated voltage regulator permits wide 4V to 18V operating voltage range
* Four levels of illumination control function
* 30-p

Applications

* four 7-segment displays are required to display the correct time output. The connections for the grids and segments are shown below, however it should be noted that the fourth segment only requires two of its segments to be driven. Additionally it should be noted that the colon can also be illumina
