Preliminary
Stresses above those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent device failure. Functionality at
or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliabil-
ity. Operating ranges define those limits between which the functionality of the device is guaranteed.

Description
Ground Pin.
RESET goes low if V
CC
falls below the reset
threshold and remains asserted for one reset timeout
period (140ms min.) after V
CC
exceeds the reset
threshold.
RESET goes high if V
CC
falls below the reset
threshold and remains asserted for one reset timeout
period (140ms min.) after V
CC
exceeds the reset
threshold.
Power supply input, 3 V, 3.3 V or 5 V.
