NOTE:
7. t LZ and t OLZ min.; t SOE and t HOE min; and t HZ and t OHZ are periodically sampled and not 100% tested. t HZ max. and t OHZ max. are measured,
with CL = 5pF, from the point when CE or OE return high (whichever occurs first) to the time when the outputs are no longer driven.
Electrical Specifications
V CC = 3.0V to 3.6V, T A = -40°C to +85°C. Parameters with MIN and/or MAX limits are 100% tested at +25°C,
