RESETZ 74
I
Chip reset: This input pin is used to reset the chip into a known state. For
normal operation, this pin is set to 1. To reset the chip, this pin is driven to 0.
This pin has an internal 30
µ
A (nom.) current source pull-up. The minimum
width of the pulse is 5
µ
S. A 0.1µF capacitor to GNDD should be connected to
this pin.
