SN74CBT3126PW Description

Short technical summary and product information.

The SN74CBT3126PW is a quadruple FET bus switch from Texas Instruments, featuring independent line switches. Each switch is disabled when its associated output-enable (OE) input is low. This device is designed for general-purpose applications and supports a bandwidth of 200 MHz.

 

Key electrical specifications include a typical on-resistance of 5000 mΩ and a maximum of 22000 mΩ. The input/output voltage ranges from 0 V to 5.5 V, with a continuous current handling capability of up to 128 mA. The operating temperature range is -40°C to 85°C.

 

This bus switch is available in a 14-TSSOP package, suitable for surface mount applications. The standard '126-type pinout is maintained, and it features TTL-compatible input levels. Latch-up performance exceeds 250 mA per JESD 17.

 

Protocols supported include Analog, I2C, I2S, JTAG, RGMII, SPI, TDM, and UART, making it versatile for various signal routing needs.
