Mil-Std-883, method 5005, subgroup 9, 10, 11.
1. V_DD = 5V±10% and C_CL = 50pF, over full operating temperature range.
2. Input Pulse V_SS 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 V_SS via 680Ω.
