Overview
The TS3A4751PWRG4 is a low-voltage, single-supply, quad SPST analog switch manufactured by Texas Instruments. It operates on a single power supply ranging from 1.6V to 3.6V and features four normally open switches capable of handling rail-to-rail analog signals. The device offers an on-state resistance of 0.9Ω maximum at 3V and 1.5Ω maximum at 1.8V. Key electrical parameters include a switching time of 14ns (Ton) and 9ns (Toff), a leakage current of 75nA maximum, and a continuous current handling capability of 100mA. It is housed in a 14-TSSOP package.
Feature Summary
- Supports bidirectional signal transmission with rail-to-rail analog signal handling capabilities.
- Provides high current processing capacity for demanding analog applications.
- Features low static power consumption suitable for battery-powered devices.
- Includes robust electrostatic discharge protection exceeding industry standards.
Applications
- Portable consumer electronics requiring low-power signal routing.
- Audio and video signal switching in mobile devices.
- Data acquisition systems utilizing low-voltage microcontrollers.
- Battery-operated equipment needing efficient power management.
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free and RoHS compliance as per Texas Instruments documentation. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the operating voltage range of 1.6V to 3.6V aligns with your system's power supply rails. Check for any recent product change notices that might affect pinout or electrical characteristics.
Selection Notes
Select this component when a quad SPST switch is required within a 1.6V to 3.6V supply range. It is appropriate for applications demanding low on-resistance and fast switching speeds. Consider the 14-TSSOP package if space constraints allow for surface-mount assembly. Compare against other TS3A series variants if different channel counts or package types are needed.
Part Context
The TS3A4751PWRG4 belongs to the TS3A4751 family of low-voltage analog switches. This family includes variants with different package options such as VQFN and X2QFN. The PWRG4 designation specifically identifies the 14-pin Thin Shrink Small Outline Package (TSSOP) variant with green/RoHS-compliant materials. It serves as a versatile solution for signal multiplexing in compact electronic designs.
Replacement Considerations
Direct pin-compatible alternatives within the same family include TS3A4751RGYR (VQFN package) and TS3A4751RUCRG4 (X2QFN package). Verify that the alternative package fits your board layout. Other TI analog switches may require level shifting or have different electrical specifications.
