Overrange pin. Normally this pin is set high. When V
is low.
Digit select pin. The digit select output goes high when the respective digit is
selected. The MSD (1/2 digit turns on immediately after an EOC pulse).
The remaining digits turn on in sequence from MSD to LSD.
To ensure that the BCD data has settled, an inter digit blanking time of two
clock periods is included.
Clock frequency divided by 80 equals multiplex rate. For example, a system
clock of 60 kHz gives a multiplex rate of 0.8 kHz.
See Figure for digit select timing diagram.
BCD data output pin. Multiplexed BCD outputs contain three full digits of
information during digit select DS

is available.
Refer to the Truth Table 5-1.
Positive power supply. This is the most positive power supply pin.
