Notes:

8. Under normal operation this pin should be tied to VD+ or DGND. Anytime the voltage on the M/SLP

pin enters the SLEEP active threshold range the device will enter the power down condition. Returning

to the active state requires elapse of the power-on reset period, the oscillator to start-up, and elapse

of the wake-up period.

9. Iout = -100 µA. This guarantees the ability to drive one TTL load. (VOH = 2.4V @ Iout = -40 µA).
