DESCRIPTION
The TS5A23157 is a dual, single-pole, double-throw (SPDT) analog switch designed to operate from 1.65 V to
5.5 V. This device can handle both digital and analog signals. Signals up to 5.5 V (peak) can be transmitted in
either direction.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are with respect to ground, unless otherwise specified.
(3) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(4) This value is limited to 5.5 V maximum.
(5) The package thermal impedance is calculated in accordance with JESD 51-7.

Leakage current measured at IN
Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation
delay between the digital control (IN) signal and analog outputs (COM/NC/NO) signal when the switch is turning ON.
tON
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the propagation
delay between the digital control (IN) signal and analog outputs (COM/NC/NO) signal when the switch is turning OFF.
tOFF
tBBM
Break-before-make time. This parameter is measured under the specified range of conditions and by the propagation
delay between the output of two adjacent analog channels (NC and NO) when the control signal changes state.
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC, NO, or
COM) output. This is measured in coulombs (C) and measured by the total charge induced due to switching of the
control input. Charge injection, QC = CL× ΔVO, CL is the load capacitance and ΔVO is the change in analog output

OISO
DESCRIPTION
OFF isolation of the switch is a measurement of OFF-state switch impedance. This is measured in dB in a specific
frequency, with the corresponding channel (NC to COM or NO to COM) in the OFF state. OFF isolation, OISO = 20 LOG
(VNC/VCOM) dB, VCOM is the input and VNC is the output.
Crosstalk is a measurement of unwanted signal coupling from an ON channel to an OFF channel (NC to NO or NO to
NC). This is measured at a specific frequency and in dB. Crosstalk, XTALK = 20 log (VNC1/VNO1), VNO1 is the input and
VNC1 is the output.
XTALK
BW
Bandwidth of the switch. This is the frequency where the gain of an ON channel is –3 dB below the dc gain. Gain is
measured from the equation, 20 log (VNC/VCOM) dB, where VNC is the output and VCOM is the input.
I+
Static power-supply current with the control (IN) pin at V+ or GND
ΔI+
This is the increase in I+ for each control (IN) input that is at the specified voltage, rather than at V+ or GND.

(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.

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)
