Figure 1. Figure 2. Figure 1 shows the timing sequence for latching the switch Figure 2 shows the Reset Pulsewidth, tRS, and the Reset Turnoff address and enable inputs. The latches are level sensitive; there- Time, tOFF, (RS). fore, while WR is held low, the latches are transparent and the Note: All digital input signals rise and fall times are measured switches respond to the address and enable inputs. This input from 10% to 90% of 3 V. tr = tf = 20 ns. data is latched on the rising edge of WR.
