Fast switching speeds, low ON-resistance, and low power-consumption make these devices ideal for singlecell battery powered applications. These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches as listed in Table 1. Table 1. Standard Products Model AS1741 AS1742 AS1743 Switch Types Two Normally Open (NO) Switches Two Normally Closed (NC) Switches One NO Switch and One NC Switch 2 Key Features !
