0.9-Ohm Low-Voltage Single-Supply Dual SPST Analog Switch - TS3A4741

TS3A4741 (ACTIVE)

0.9-Ohm Low-Voltage Single-Supply Dual SPST Analog Switch

Description

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.

Features

  • Low ON-State Resistance (Ron)
    • 0.9-Ω Max (3-V Supply)
    • 1.5-Ω Max (1.8-V Supply)
  • 0.4-Ω Max Ron Flatness (3-V Supply)
  • 1.6-V to 3.6-V Single-Supply Operation
  • Available in SOT-23 and VSSOP Packages
  • High Current-Handling Capacity (100 mA Continuous)
  • 1.8-V CMOS Logic Compatible (3-V Supply)
  • Fast Switching: tON = 14 ns, tOFF = 9 ns
