For more details, read our Order Terms and Conditions. In that case, you want to cascade the encoder chips so that instead of having two sets of three bit outputs, you have a single four bit output. Below is the schematic for how to cascade two s to give a single 4 bit output. Ideally you want to choose a large value that works consistently. If you need to update a browser, you might try Firefox which is free open source available for several platforms Since this page uses cascading style sheets for its layout, it will look best with a browser which supports the specifications as fully as possible.
