Multiple A139x devices can be connected to a single micro-
processor or A-to-D converter input. In this case, a single
device is periodically triggered and put into active mode by
the microprocessor. While one A139x device is in active
mode, all of the other A139x devices must remain in sleep
mode. While these devices are in sleep mode, their outputs
are in a high-impedance state. In this circuit configuration,
the microprocessor reads the output of one device at a time,

according to microprocessor input to the S ¯ ¯ L ¯ ¯ E ¯ ¯ E ¯ ¯ P ¯ pins.
When multiple device outputs are connected to the same
microprocessor input, pulse timing from the microproces-
sor (for example, lines A1 through A4 in figure 6) must be
configured to prevent more than one device from being in the
awake mode at any given time of the application. A device
output structure can be damaged when its output voltage is
forced above the device supply voltage by more than 0.1 V.
