Pin Description
Bidirectional Interface Pin. A time delay between when the part is initiated externally by pulling I/O low and
when the part subsequently pulls I/O low, is proportional to absolute temperature (°K).
I/O6
Time-Select Pins. Set the time delay factor by connecting TS1 and TS0 to either V
DD
or GND. See Table 1.TS0, TS14, 5
No Connect. Connect pin to GND or leave open.N.C.3
