Mil-Std-883, method 5005, subgroup 9, 10, 11.
1. VDD = 5V±10% and CCL = 50pF, over full operating temperature range.
2. Input Pulse VSS to 3.0 Volts.
3. Times Measurement Reference Level 1.5 Volts.
4. DSN = Data Strobe Pulse Width.
5. Measured by a 1.0 Volt change in output voltage. Outputs tied to VSS via 680Ω.
