ELECTRICAL CHARACTERISTICS
MAX (unless otherwise noted)
1 Inclusive of 25C tolerance, operating temperature range, input voltage change, load change,
reflow freq. shift and one year aging.
2 Inclusive of 25C tolerance and operating temperature range.
3 An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
Notes: A 0.01F capacitor should be placed between Vdd (Pin 4) and GND (Pin2) to minimize
power supply noise.
Dimensional drawing is for reference to critical specifications defined by size measurements.
Certain non-critical visual attributes, such as side castellations, reference pin shape, etc. may
vary.
All specifications subject to change without notice.
