Ensuring That RESET is Valid Down to V
CC
= 0V
When V
CC
falls below 1.1V, the IMP705-708 RESET output no
longer pulls down; it becomes indeterminate. To avoid the possi-
bility that stray charges build up and force RESET to the wrong
state, a pull-down resistor should be connected to the RESET pin,
thus draining such charges to ground and holding RESET
low. The resistor value is not critical. A 100k
resistor will pull
RESET to ground without loading it.
Bi-directional Reset Pin Interfacing
The IMP705/6/7/8 can interface with
μ
P/
μ
C bi-directional reset
pins by connecting a 4.7k
resistor in series with the RESET
output and the
μ
P/
