No Connection.
Do not connect any signal to this pin.
Reference Voltage 2.
Must be externally connected directly to
the VREF1 pin. Must be decoupled with a 4.7
μ
F capacitor as
shown in Figure 2.
Active-Low Power-Down.
When tied low, the DS21S07A
enters a power-down mode. Contains an internal 50k
pullup
resistor. Strap low to deactivate the DS21S07A; leave open
circuited to activate the DS21S07A
