The schematic shows that wiring the LCD to the HEF4094 is a simple operation. It has been drawn in a way that makes possible to develop this as part of a single sided PCB including a variable resistor to control the LCDs contrast. Note that the pinout of the LCD module may differ slightly from the pinout depicted; some LCD modules have pins 15 and 16 on the left side, before pin 1.
