SN74CBTLV3126PWR Description

Short technical summary and product information.

The SN74CBTLV3126PWR 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.

 

Key electrical specifications include a typical on-resistance of 5Ω and a maximum on-resistance of 40Ω. The switch operates over a voltage range of 2.3V to 3.6V with a maximum continuous current of 128mA. It supports a bandwidth of 200 MHz and features low off-state leakage current of 1µA.

 

The device is designed for rail-to-rail switching on data I/O ports and supports partial-power-down mode operation. Latch-up performance exceeds 100mA per JESD 78, Class II.

 

Packaged in a 14-TSSOP, the SN74CBTLV3126PWR is suitable for surface mount applications. The operating temperature range is -40°C to 85°C.
