Reset  
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.

Notes:  
1. TA is the “instant on” case temperature.  
2. See the last page of this specification for Group A subgroup testing information.  
3. The VIH and VIL 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 VSS  
.
4. Test no more than one output at a time for not more than one second.  
5. 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.  
6. All input signals are connected to VCC. All outputs are unloaded.
