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. 2 Applications Power Routing Battery-Powered Systems Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Communications Circuits PCMCIA Cards Cellular Phones Modems Hard Drives Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TS3A4741 SOT (8) VSSOP (8) 2.90 mm × 1.63 mm 3.00 mm × 3.00 mm TS3A4742 SOT (8) VSSOP (8) 2.90 mm × 1.63 mm 3.00 mm × ...
