TS3A4742 0.8Ω 低电压单电源双路 SPST 模拟开关

The TS3A4741/TS3A4742 are low ON-state resistance (ron), low-voltage, dual single-pole/single-throw (SPST) 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
