The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
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
.
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
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. I
1(typical) = (25 mA+(freq –20 MHz)*(1.0 mA/MHz)).
All inputs = V
– 0.2V, except RCLK and WCLK (which are switching at frequency = 20 MHz), and FL/RT which is at V
ss
. All outputs are unloaded.
Tested initially and after any design changes that may affect these parameters.
