6 Ω, L o w - Vo l ta g e , D u a l S P D T A n a l o g S w i t c h Product Brief 1 General Description The AS1746 is a low on-resistance (RON), low-voltage, dual-single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.
8 to +5.
5V supply.
The device features a 0.
5Ω (max) RON for normally closed (NC) switches and a 0.
6Ω (max) RON for normally open (NO) switches using a +2.
7V supply.
The AS1746 features break-before-make switching (2ns) with tON = 50ns and tOFF = 30ns (using a +2.
7V supply).
The digital logic inputs are 1.
8V logic-compatible with +2.
7 to +3.
3V supplies.
The AS1746 is available in a TDFN-10 (3x3mm) package, a MSOP-10 and a WL-CSP-10 package.
