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.

Test Conditions
Cascaded - Connected to RXO of previous device.
Not Cascaded - Tied to V
Cascaded - Connected to RXI of next device.
Resets device to empty condition. A reset is required before an initial read or write
operation after power-up.
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.
Dual-Mode Pin
Asynchronous Almost Empty/Almost Full flags - tied to V
Synchronous Almost Empty/Almost Full flags - tied to V
(Almost Empty synchronized to RCLK, Almost Full synchronized to WCLK.)
