When Pin 8 ( DISABLE ) is higher than Pin 1 (LOGIC REFERENCE) by approximately 2 V or more, the part is enabled. When Pin 8 is brought down to within about 1.5 V of
Pin 1, the part is disabled. (See the Specifications tables for exact disable and enable voltage levels.) If the disable feature is not going to be used, Pin 8 can be tied to
+V
S
or a logic high source, and Pin 1 can be tied to ground or logic low. Alternatively, if Pin 1 and Pin 8 are not connected, the part is in an enabled state.
