SN74CB3Q3125PWR Description

Short technical summary and product information.

The SN74CB3Q3125PWR from Texas Instruments is a high-performance quadruple FET bus switch designed for low-voltage, high-bandwidth applications. This device features a 1:1 SPST configuration across 4 independent circuits, supporting a bandwidth of up to 500 MHz. It operates within a supply voltage range of 2.3V to 3.6V and maintains a low ON-state resistance of 4000 mΩ (typical).

 

This bus switch is capable of rail-to-rail switching on data I/O ports, supporting 0V to 5V signaling levels with a 3.3V VCC, and 0V to 3.3V switching with a 2.5V VCC. It offers bidirectional data flow with near-zero propagation delay and low input/output capacitance (4 pF typical) to minimize loading and signal distortion. The SN74CB3Q3125PWR is housed in a 14-TSSOP package and is designed for surface mount applications, operating across a temperature range of -40°C to 85°C.

 

Key features include 5V tolerant I/Os, low power consumption (0.3 mA typical), and support for various protocols such as Analog, I2C, I2S, JTAG, RGMII, SPI, TDM, and UART. It also includes ESD protection tested per JESD 22, with 2000V Human-Body Model and 1000V Charged-Device Model ratings.
