SN74CBTLV3125NSRG4

Overview

The SN74CBTLV3125NSRG4 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 supports data rates up to 600 Mbps. The device features four independent switches with configurable polarity control inputs, allowing for flexible signal routing in digital systems. It utilizes an 8-pin VSSOP package designed for surface-mount applications.

Feature Summary

• Supports low-voltage operation from 2.3 V to 3.6 V
• Provides four independent single-pole single-throw analog switches
• Configurable polarity control inputs for bidirectional signal flow

Applications

• Portable equipment requiring low power consumption
• Battery-powered consumer electronics
• High-speed data line switching

Procurement Notes

Verify the specific suffix 'SRG4' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with the target PCB footprint for the 8-pin VSSOP package before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require low on-resistance and minimal power dissipation in portable devices. It serves as a suitable alternative to standard CMOS switches where lower operating voltages are necessary. Verify that the required signal bandwidth does not exceed the specified limits for optimal performance.

Part Context

This part belongs to the SN74CBT family of low-voltage bus switches. It is functionally similar to the SN74CBTLV3125 series but packaged in a compact VSSOP form factor. The device is intended for use in space-constrained designs where efficient signal management and low standby current are critical requirements.

Replacement Considerations

Direct substitutes include the SN74CBTLV3125PWR and SN74CBTLV3125DGR. Verify pinout compatibility and package dimensions before replacing the original component in existing designs.
