Overview
The TS5A21366RSER is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It features a low on-state resistance of 0.75 ohms and operates within a supply voltage range of 1.65 V to 5.5 V. The device supports 1.8-V compatible input logic, enabling direct interfacing with low-voltage controllers. Key electrical parameters include a maximum propagation delay of 72 ns and an off-isolation characteristic suitable for signal routing applications. It is housed in an 8-pin VSSOP package and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Dual SPST configuration providing independent signal path control
- Low on-resistance ensures minimal signal attenuation
- Compatible with 1.8-V logic levels for flexible system integration
Applications
- Portable equipment signal routing
- Audio and video signal switching
- Communication equipment interface protection
Procurement Notes
Verify the specific suffix RSER against the official datasheet to confirm the reel packaging quantity and tape-and-reel specifications. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the manufacturer's latest documentation to confirm compliance with current RoHS directives and environmental standards before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel analog switch with low on-resistance and 1.8-V logic compatibility is required. Compare the 0.75-ohm on-resistance and 72-ns propagation delay against alternative devices to ensure signal integrity requirements are met. Verify that the VSSOP-8 package dimensions fit the target PCB layout constraints and thermal management needs.
Part Context
This component belongs to the TS5A21366 family of analog switches designed for portable applications. The series emphasizes low power consumption and small form factor solutions. The RSER suffix specifically denotes the reel-based packaging format used for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers include TS5A21366DCUR and TS5A21366RSER. These variants share identical functional specifications but differ in packaging type or reel configuration. Verify pinout compatibility and package dimensions before substituting.
