VFD Driver/Controller IC

PT6332

Note:

*: These diodes are required to reliably recognize multiple key presses on the KS5 line when the IC is

set to sleep mode with only KS5 set to high as in the example above. That is, they prevent incorrect

recognition of key pressed due to sneak currents arising from simultaneous presses of keys on the

KS1 through KS4 lines.
