Notes:
1682A–10/01
1. Read Cycle occurs whenever a high on the SWE and SOE is low, while SUB and/or SLB and SCS1 and SCS2 are in active
2. SOE = V
3. Transition is measured + 200 mV from steady state voltage. This parameter is sampled and not 100% tested.
4. SCS1 in high for the standby, low for active. SCS2 in low for the standby, high for active. SUB and SLB in high for the
