SN74CBTLV3126DBQR Description

Short technical summary and product information.

The SN74CBTLV3126DBQR from Texas Instruments is a quadruple FET bus switch featuring independent line switches. Each switch is disabled when the associated output-enable (OE) input is low. This device is fully specified for partial-power-down applications using Ioff, ensuring that damaging current does not backflow through the device when powered down. It offers isolation during power off.

 

Key electrical specifications include a bandwidth of 200 MHz, a typical on-resistance of 5 Ohms, and a maximum on-resistance of 40 Ohms. The input/output voltage range is from 0V to 3.6V. It supports various protocols including Analog, I2C, I2S, JTAG, RGMII, SPI, TDM, and UART. The operating temperature range is -40°C to 85°C.

 

Available in multiple package types such as TSSOP, SSOP, VQFN, SOIC, WQFN, and TVSOP, this bus switch is suitable for a wide range of applications requiring flexible signal routing and power-down isolation. The latch-up performance exceeds 100mA per JESD 78, Class II.
