•Communication Circuits•1.65-V to 3.6-V Single-Supply Operation
•Modems•Latch-Up Performance Exceeds 100 mA Per
•Hard DrivesJESD 78, Class II
•Computer Peripherals•ESD Performance Tested Per JESD 22
•Wireless Terminals and Peripherals– 2000-V Human-Body Model(A114-B, Class II)– 1000-V Charged-Device Model (C101)
The TS3A24157 is a dual single-pole double-throw (SPDT) analog switch that is designed to operate from 1.4 Vto 3.6 V. The device offers low ON-state resistance and excellent ON-state resistance matching with thebreak-before-make feature, to prevent signal distortion during the transfer of a signal from one channel toanother. The device has excellent total harmonic distortion (THD) performance and consumes very low power.These features make this device suitable for portable audio applications.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
