SN74CBTLV3126DR Description

Short technical summary and product information.

The SN74CBTLV3126DR is a quadruple FET bus switch from Texas Instruments, designed for versatile signal routing applications. Each independent line switch can be controlled via an output-enable (OE) input, disabling the switch when OE is low. This device is fully specified for partial-power-down applications utilizing the Ioff feature, which prevents damaging current backflow when the device is powered down, ensuring isolation during power off.

 

With a bandwidth of 200 MHz and low on-resistance, the SN74CBTLV3126DR is suitable for various digital interfaces including I2C, SPI, and UART. It supports rail-to-rail switching on data I/O ports and operates within an input/output voltage range of 0V to 3.6V. The device is specified for an operating temperature range of -40°C to 85°C.

 

Available in multiple package options such as TSSOP, SSOP, VQFN, SOIC, WQFN, and TVSOP, the SN74CBTLV3126DR offers flexibility for different PCB layouts and space constraints. Its latch-up performance exceeds 100mA per JESD 78, Class II, indicating robust design for demanding applications.
