A snubber isn't needed to eliminate false operation ofthe TRIAC driver because of the high static and com-mutating dv/dt with loads between l.0 and 0.8 powerfactors. When inductive loads with power factors lessthan 0.8 are being driven, include a RC snubber or asingle capacitor directly across the device to dampthe peak commutating dv/ dt spike. Normally a com-mutating dv/dt causes a turning-off device to stay ondue to the stored energy remaining in the turning-offdevice.

Instructions, addresses, and write data are clocked intothe DI pin on the rising edge of the clock (SK). The DOpin is normally in a high impedance state except whenreading data from the device, or when checking theready/busy status after a write operation.
