Power Down.
When tied low, the DS21S07A enters a power-
down mode. Contains an internal 50K pull–up. Strap low to deac-
tivate the DS21S07A, leave open circuited to activate the
DS21S07A.

N/A
HS–GND
Heat Sink Ground.
Internally connected to the mounting pad.
Should be either grounded or electrically isolated from other cir-
cuitry.
