digit worst cast) should be avoided, since this loss is in addition to
any inaccuracies or load regulation limitations of the power supply.
The 5 volt power supply for the displays should be the same one
supplying V
CC
to all logic devices which drive the display devices.
If a separate supply must be used, then local buffers using hex
non-inverting gates should be used on all inputs and these buffers
should be powered from the display power supply. This precau-
tion is to avoid logic inputs higher than display V
up or line transients.

Interfacing the 3416
A general and straightforward interface circuit is shown in Figure
6. This scheme can easily interface to μP systems or any other
systems which can provide the seven data lines, appropriate
address, and control lines.

Parallel I/O
The parallel I/O device of a microprocessor can easily be con-
nected to the circuit in Figure 6. One eight bit output port can
provide the seven input data bits and the cursor (CU).
Another eight bit output port can contain the address and
chip enable information and the other control signals.
