* N = number of devices that are cascaded. For example, to drive 10 digits, 2 devices are cascaded; therefore, N = 2. To drive 35 digits, seven
devices are cascaded; therefore N = 7.

NOTE: R1 limits the maximum current to avoid damaging the display and/or the MC14489B
due to overheating. See the Thermal Considerations section. An 1/8 watt resistor
may be used for R1. R2 is a 1 k
or 5 k
potentiometer (
≥
1/8 watt). R2 may be a
light–sensitive resistor.
