The TS3A4741 and TS3A4742 are bi-directional, 2-channel single-pole/single-throw (SPST) analog switches with low ON-state resistance (Ron), low-voltage, that operate from a single 1.6-V to 3.6-V supply. These devices have fast switching speeds, handle rail-to-rail analog signals, and consume very low quiescent power.
The digital logic input is 1.8-V CMOS compatible when using a single 3-V supply.
The TS3A4741 has two normally open (NO) switches, and the TS3A4742 has two normally closed (NC) switches.
