VIH
Minimum input voltage for logic high for the control input (IN)
VIL
Maximum input voltage for logic low for the control input (IN)
VI
Voltage at the control input (IN)
IIH, IIL
Leakage current measured at the control input (IN)
tON
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 output (COM or NC) signal when the switch is turning ON.
tOFF
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 output (COM or NC) signal when the switch is turning OFF.
QC
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC or COM) output.
This is measured in coulomb (C) and measured by the total charge induced due to switching of the control input.
Charge injection, QC = CL × ∆VCOM, CL is the load capacitance, and ∆VCOM is the change in analog output voltage.
CNC(OFF)
CNC(ON)
Capacitance at the NC port when the corresponding channel (NC to COM) is OFF
CCOM(OFF)
CCOM(ON)
Capacitance at the COM port when the corresponding channel (COM to NC) is OFF
CI
Capacitance of control input (IN)
OISO
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) in the OFF state.
BW
Bandwidth of the switch. This is the frequency in which the gain of an ON channel is −3 dB below the DC gain.
THD
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio of root mean
square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of the fundamental harmonic.
I+
Static power-supply current with the control (IN) pin at V+ or GND
Capacitance at the NC port when the corresponding channel (NC to COM) is ON
Capacitance at the COM port when the corresponding channel (COM to NC) is ON

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
