Notes:
1. TA is the “instant on” case temperature.
2. VCC range for commercial -10 ns is 3.3V ±150mV.
3. See the last page of this specification for Group A subgroup testing information.
4. 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.
5. Input signals switch from 0V to 3V with a rise/fall time of less than 3 ns, clocks and clock enables switch at 20 MHz, while data inputs switch at 10 MHz. Outputs
are unloaded.
6. All inputs = VCC – 0.2V, except RCLK and WCLK (which are at frequency = 0 MHz), and FL/RT which is at VSS. All outputs are unloaded.
7. Tested initially and after any design changes that may affect these parameters.
