Resets device to empty condition. A reset is required before an initial read or write
operation after power-up.
OE
Output Enable
I
When OE is LOW, the FIFO’s data outputs drive the bus to which they are con-
nected. If OE is HIGH, the FIFO’s outputs are in High Z (high-impedance) state.

T
is the “instant on” case temperature.
See the last page of this specification for Group A subgroup testing information.
The V
and V
specifications apply for all inputs except WXI, RXI. The WXI, RXI pin is not a TTL input. It is connected to either RXO, WXO of the
previous device or V
.
Test no more than one output at a time for not more than one second.
Input signals switch from 0V to 3V with a rise/fall time less than 3 ns, clocks and clock enables switch at 20 MHz, while the data inputs switch at 10 MHz.
Outputs are unloaded.
All input signals are connected to V
CC
. All outputs are unloaded.
