X = “Don't Care,” 1 = Logic HIGH, 0 = Logic LOW.
The SRAM always initiates a Read cycle when ADSP asserted, regardless of the state of GW, BWE, or BW
after the ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH prior to the start of the Write cycle to allow the outputs to three-state. OE
is a “don't care” for the remainder of the Write cycle.
OE is asynchronous and is not sampled with the clock rise. It is masked internally during Write cycles. During a Read cycle DQ = High-Z when OE is inactive
or when the device is deselected, and DQ = data when OE is active.
Minimum voltage equals –2.0V for pulse durations of less than 20 ns.
