PIN NAME FUNCTION
1
V
DD
Positive Supply Voltage
2 GND Ground
3 N.C. No Connect. Connect pin to GND or leave open.
4, 5 TS0, TS1 Time-Select Pins. Set the time delay factor by connecting TS1 and TS0 to either V
DD
or GND. See Table 1.
6 I/O
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).
