NOTES:
1. All timing measurements are defined at the point of signal crossing VDD / 2.
2. These parameters are periodically sampled and are not 100% tested.
3. The 24k
+20% resistors are configured as 4 resistors in parallel which would provide a measured value between VREFH and VREFL of 6k +20%. The individual 24k
resistors are not measurable but guaranteed by design and verification of the 6k
+20% value.
AC ELECTRICAL CHARACTERISTICS:
VDD = +2.7V to +5.5V, VREFH = VDD, VREFL = 0V, unless otherwise specified
CL=100pF,
