7.7 Transition Time

Transition time is defined as the time taken by the output of the device to rise (to 90% of the transition) or fall (to

10% of the transition) after the select signal (SELx) has fallen or risen to 50% of the transition. Figure 7-8 shows

the setup used to measure transition time, denoted by the symbol tTRAN.

7.8 Fault Response Time

Fault response time (tRESPONSE) measures the delay between the source voltage exceeding the supply voltage

(VDD or VSS) by 0.5 V and the drain voltage failing to 50% of the maximum output voltage. Figure 7-9 shows the

setup used to measure tRESPONSE.
