to ensure that logic inputs are maintained at either
VD+ ar DGND potential when SLEEP is low.
Note that battery life could be shortened if the
+5 V supply drops slowly during power-down. As
the supply drops below the battery voltage but not
yet below the logic threshold of the SLEEP pin,
the battery will be supplying the CS5501/CS5503
at full power (typically 3 mA). Faster transitions
at SLEEP can be triggered using a resistive di-
vider or a simple resistor network to generate the
SLEEP input from the +5 V supply.
Output Loading Considerations
To maximize performance of the CS5501/
CS5503, the output drive currents from the digital
output lines should be minimized. It is recom-
mended that CMOS logic gates (4000B, 74HC,
etc.) be used to provide minimum loading. If it is
necessary to drive an opto-isolator the outputs of
the CS5501/CS5503 should be buffered. An easy
means of driving the LED of an opto-isolator is to
use a 2N7000 or 2N7002 low cost FET.
