AC Waveforms for Read Operation
(1)
Notes: 1. Timing measurement references are 0.8V and 2.0V. Input AC drive levels are 0.45V and 2.4V, unless otherwise specified.
2. OE
may be delayed up to t

.
4. This parameter is only sampled and is not 100% tested.
5. Output float is defined as the point when data is no longer driven.
6. When reading a 27BV4096, a 0.1
µ
F capacitor is required across V
CC
and ground to suppress spurious voltage transients.
