AC Characteristics for Operation
NOTE
: 1. If CE goes high within 30ns after the rising edge of the last RE, R/B will not return to V
OL
.
2. The time to Ready depends on the value of the pull-up resistor tied R/B pin.
3. To break the sequential read cycle, CE must be held high for longer time than tCEH.
