Overview
The SN74CBTLV3125RGYR is a low-voltage quadruple FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features four independent single-pole double-throw (SPDT) analog switches. The device utilizes a 14-pin TSSOP package with a maximum width of 4.40 mm. Key electrical characteristics include a maximum on-resistance of 12 Ohms and a maximum propagation delay of 150 ps. It supports a wide operating temperature range from -40°C to +85°C and is RoHS compliant.
Feature Summary
- Provides four independent SPDT analog switches for signal routing
- Operates at low voltages between 2.3 V and 3.6 V
- Features low on-resistance for minimal signal attenuation
- Supports bidirectional data flow
Applications
- Portable equipment requiring low-voltage signal switching
- Battery-powered systems
- Consumer electronics
- Communications equipment
Procurement Notes
Verify the specific suffix 'RGYR' corresponds to the 14-pin TSSOP package with reel packaging. Confirm the manufacturer is Texas Instruments, as other vendors may produce similar part numbers. Ensure compliance with RoHS standards if required by your project specifications. Check for moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this component when designing circuits that require multiple independent analog switches in a compact surface-mount package. It is suitable for applications needing low power consumption and operation below 3.6 V. Compare on-resistance and propagation delay against system timing requirements. Consider the TSSOP footprint availability in your PCB layout constraints.
Part Context
This component belongs to the SN74CBTLV3125 family of low-voltage bus switches. It is designed for high-speed signal switching in portable and battery-operated devices. The device offers a cost-effective solution for managing multiple signal paths in space-constrained environments.
Replacement Considerations
SN74CBTLV3125PWR is a pin-compatible alternative in the same TSSOP-14 package but may differ in tape and reel specifications. Verify functional equivalence regarding voltage ranges and electrical parameters before substitution.
