IDT71V25761, IDT71V25781, 128K x 36, 256K x 18, 3.3V Synchronous SRAMs with
2.5V I/O, Pipelined Outputs, Burst Counter, Single Cycle Deselect Commercial and Industrial Temperature Ranges
AC Electrical Characteristics
(V
DD
= 3.3V ±5%, Commercial and Industrial Temperature Ranges)
NOTES:
1. Measured as HIGH above V
IH
and LOW below V
IL
.
2. Transition is measured ±200mV fromsteady-state.
3. Device must be deselected when powered-up fromsleep mode.
4. t
CFG
is the mnimumtime required to configure the device based on the
LBO
input.
LBO
is a static input and must not change during normal operation.
5. Commercial temperature range only.
