Storage Temperature ................................ –65°C to +150°C
Ambient Temperature with Power Applied . –55°C to +125°C
Supply Voltage to Ground Potential ............... –0.5V to +7.0V
DC Voltage Applied to Outputs
in High Z State ............................................... –0.5V to +7.0V
DC Input Voltage
..........................................−0.5V to V
CC+0.5V
Output Current into Outputs (LOW)............................. 20 mA
Static Discharge Voltage............................................ >2001V
(per MIL–STD–883, Method 3015)
Latch-Up Current ..................................................... >200 mA
Notes:
1.
The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
2.
TA is the “Instant On” case temperature.
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.
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.
6.
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. ICC1(typical) = (25 mA+(freq –20 MHz)*(1.0 mA/MHz)).
7.
All inputs = VCC – 0.2V, except RCLK and WCLK (which are switching at frequency = 20 MHz), and FL/RT which is at Vss. All outputs are unloaded.
8.
Tested initially and after any design changes that may affect these parameters.
9.
Tested initially and after any process changes that may affect these parameters.
