• Manufacturer: Analog Devices, Inc.

ADG428/ADG429
TIMING DIAGRAMS
Figure 1 shows the timing sequence for latching the switch
address and enable inputs. The latches are level sensitive; there-
fore, while WR is held low, the latches are transparent and the
switches respond to the address and enable inputs. This input
data is latched on the rising edge of WR.
