Description

SN76477N DEMO BOARD

Demo board based on Wikipedia information about SN76477N IC.

Switchts and their associated components are intended be to placed on additional PCBs ( Search for SW PANEL at PCBWAY).

All rotatory switchs are RS26 1P12T to make it easier. Unused positions may cause "to air" the pin.

Obviously, they can be used the exactly switch positions for each one to avoid this.
