• Hard Drives

• 1.8-V CMOS Logic Compatible (3-V Supply)

• Fast Switching: t

analog switches 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. Both devices are available in 8-pin SOT-23 and MSOP packages.
