Overview
The TS3A5017QRGYRQ1 is a dual-channel, 4:1 analog switch designed for automotive applications. It operates on a single supply voltage ranging from 2.3 V to 3.6 V and features bidirectional signal paths. The device supports powered-off protection, maintaining high impedance when VCC is 0 V. Key electrical parameters include an ON-state resistance of 11 Ω (typical) at 3.3 V, with a maximum channel-to-channel matching of 1 Ω. It exhibits low charge injection of 5 pC and a bandwidth of 165 MHz. The component is housed in a 16-pin VQFN package measuring 4.00 mm by 3.50 mm.
Feature Summary
- AEC-Q100 qualified for automotive environments with extended temperature range capabilities
- Powered-off protection ensures high-impedance state when supply voltage is absent
- Low ON-state resistance and minimal charge injection support high-speed signal routing
- Bidirectional switching handles both digital and analog signals effectively
Applications
- Sample-and-hold circuits
- Infotainment audio and video signal routing
- Telematics control units
Procurement Notes
Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the component meets AEC-Q100 requirements for the intended automotive application. Cross-reference the datasheet revision history to confirm compatibility with existing design specifications before finalizing procurement orders.
Selection Notes
Select this component for designs requiring dual SP4T switching within a compact footprint. Verify that the system supply voltage falls within the 2.3 V to 3.6 V operating range. Consider the thermal resistance characteristics if the device will operate near the upper limit of the specified temperature range.
Part Context
This part belongs to the TS3A5017-Q1 family of analog switches manufactured by Texas Instruments. It is specifically engineered for automotive systems where reliability and signal integrity are critical. The Q1 designation indicates qualification for automotive use, distinguishing it from standard commercial variants.
Replacement Considerations
Direct substitutes within the same family include TS3A5017RSVR, TS3A5017DR, and TS3A5017PWR. These alternatives share identical electrical specifications but differ in package style, such as UQFN, SOIC, or TSSOP. Verify pinout compatibility and thermal performance when substituting.
