Overview
The TS5A23157RSER is a dual single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments, designed for low-voltage operation. It features a low on-resistance of 10 ohms and supports a supply voltage range from 1.65 V to 5.5 V. The device handles digital and analog signals with bidirectional transmission capabilities up to 5.5 V peak. Key electrical parameters include an on-time of 5.7 ns, off-time of 3.8 ns, bandwidth of 220 MHz, and charge injection of 7 pC. It operates within a temperature range of -40°C to +85°C and is housed in a UQFN-10 package measuring 1.5x2 mm.
Feature Summary
- Low on-resistance of 10 Ω for efficient signal transmission
- Control inputs rated for 5 V tolerance
- Guaranteed break-before-make switching to prevent glitches
- Latch-up performance exceeding 100 mA per JESD 78 Class II
Applications
- Sampling and hold circuits
- Battery-powered equipment
- Audio and video signal routing
- Communication circuitry
Procurement Notes
Verify the specific suffix RSER corresponds to the UQFN-10 package and reel packaging configuration. Confirm that the component meets the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the 1.65 V to 5.5 V supply voltage constraints during system design validation.
Selection Notes
Select this component when a dual SPDT switch with low on-resistance is required for low-voltage systems. It is suitable for applications needing bidirectional signal handling and 5 V tolerant control logic. Consider the UQFN-10 package size for space-constrained designs requiring small footprints.
Part Context
This part belongs to the TS5A23157 family of dual SPDT analog switches from Texas Instruments. Variants such as TS5A23157DGSR offer different packaging options like MSOP-10, while automotive-grade versions like TS5A23157QDGSRQ1 provide extended temperature ranges and AEC-Q100 qualification. The RSER suffix specifically denotes the UQFN-10 form factor.
Replacement Considerations
TS5A23157DGSR offers identical electrical specifications but utilizes an MSOP-10 package instead of UQFN-10. For automotive applications requiring higher temperature tolerance, TS5A23157QDGSRQ1 is a qualified alternative with an extended range up to 125°C.
