Notes:
1. Selectable parameter specified by part number. See Section 3. "Ordering Information" on page 7 for further details.
2. OE pin includes a 17 k
pullup resistor to VDD. Pulling OE to ground causes outputs to tristate.
3. If the device is powered up below –20 C and the ambient temperature rises by approximately 105 C during normal
operation, the device will perform a one-time recalibration. The output is squelched for approximately 2–3 ms during
this recalibration.
