Overview
The SN74CBTLV3126DR 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 channels configured as 1 x 1:1 switches. The device provides a maximum on-resistance of 40 Ohms and supports a bandwidth of 200 MHz. It functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a 14-pin SOIC-Narrow (SOIC-14) surface-mount format, it draws a maximum supply current of 20 uA.
Feature Summary
- Provides powered-off protection to prevent high leakage currents when the device is unpowered
- Supports SPI and JTAG signals for reliable data transmission in digital systems
- Features low on-resistance for efficient signal routing with minimal voltage drop
Applications
- Portable equipment requiring low power consumption
- Consumer electronics utilizing SPI interfaces
- JTAG debugging and programming circuits
Procurement Notes
Verify the specific package variant against design requirements, as the base part number may appear in different housing options such as TSSOP or TVSOP. Confirm that the 2.3 V to 3.6 V supply range aligns with the target system voltage. Ensure the 40 Ohm on-resistance meets signal integrity standards for the intended application frequency.
Selection Notes
Select this component for applications requiring multiple bidirectional bus switches in a compact footprint. The SN74CBTLV3126DR is suitable where low voltage operation and powered-off protection are critical. Compare channel count and package size against alternatives like the SN74CBT3125 if higher speed or different pin counts are needed.
Part Context
This device belongs to the SN74CBTLV series of low-voltage bus switches designed for portable and battery-powered applications. It complements other logic families by offering high-speed switching with minimal power impact. The quadruple configuration allows for efficient management of multiple data lines within a single integrated circuit.
Replacement Considerations
The SN74CBTLV3126PWR serves as a direct functional alternative with identical electrical characteristics but utilizes a TSSOP-14 package instead of SOIC-14. Verify pin compatibility and thermal performance before substituting.
