Description
The TS5A4595 is a single-pole single-throw (SPST)
analog switch that is designed to operate from 2 V to
5.5 V. This device can handle both digital and analog
signals, and signals up to V+ can be transmitted in either
direction.

VCOM
Voltage at COM
VNC
Voltage at NC
ron
Resistance between COM and NC ports when the channel is ON
ron(flat)
Difference between the maximum and minimum value of ron in a channel over the specified range of conditions
INC(OFF)
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the OFF state
INC(ON)
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output (COM)
open
ICOM(OFF)
Leakage current measured at the COM port, with the corresponding channel (COM to NC) in the OFF state
ICOM(ON)
Leakage current measured at the COM port, with the corresponding channel (COM to NC) in the ON state and the output (NC)
open
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, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
