ADG528F TIMING DIAGRAMS
Figure 2 shows the timing sequence for latching the switch This input data is latched on the rising edge of WR. Figure 3 address and enable inputs. The latches are level sensitive; shows the reset pulse width, tRS, and the reset turnoff time, tOFF therefore, while WR is held low, the latches are transparent (RS). Note that all digital input signals rise and fall times are and the switches respond to the address and enable inputs. measured from 10% to 90% of 3 V. tR = tF = 20 ns.
