Overview
The TS3A4751RGYR is a quad single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.6V to 3.6V and features four normally open channels with a maximum on-resistance of 900 milliohms at 3V. The device supports rail-to-rail analog signal handling and offers a -3dB bandwidth of 125MHz. Key electrical parameters include a charge injection of 3pC, off-state leakage current of 2nA, and channel-to-channel matching of 30 milliohms. Switching times are specified as 14ns for turn-on and 9ns for turn-off. It is housed in a 14-VQFN package measuring 3.5x3.5mm.
Feature Summary
- Low on-resistance ensures minimal signal loss across the conduction path.
- Rail-to-rail capability allows accurate transmission of full-scale analog signals.
- Ultra-low static power consumption supports battery-operated applications.
- High electrostatic discharge protection safeguards against human body and machine model events.
Applications
- Portable multimedia devices requiring low-power signal routing
- Audio and video signal switching in consumer electronics
- Mobile phone camera module interfacing
- Personal digital assistants and handheld instruments
Procurement Notes
Verify the complete part number including the suffix RGYR to confirm the specific VQFN package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure the ordering quantity matches the required reel or cut tape specifications provided by the supplier.
Selection Notes
Select this component when designing circuits that require multiple independent analog switches within a compact footprint. The 1.6V minimum operating voltage makes it suitable for modern low-voltage logic systems. Consider the 900 milliohm on-resistance limit when calculating signal attenuation for high-impedance sources.
Part Context
This device belongs to the TS3A4751 family of low-voltage analog switches. It shares core electrical characteristics with variants such as TS3A4751RUCR and TS3A4751PWR, differing primarily in physical packaging. The RGYR suffix specifically denotes the 14-pin VQFN form factor designed for space-constrained surface-mount assemblies.
Replacement Considerations
Direct pin-compatible alternatives within the same series include TS3A4751RUCR and TS3A4751PWR. Verify that the substitute package type meets the mechanical constraints of the existing printed circuit board layout before implementation.
