SN74CB3Q3384APWR Description

Short technical summary and product information.

The SN74CB3Q3384APWR from Texas Instruments is a high-bandwidth FET bus switch designed for general-purpose applications. It offers a 1:1 switching configuration with 10 channels, supporting bidirectional data flow with near-zero propagation delay.

 

Key electrical characteristics include a high-bandwidth data path up to 500 MHz and low on-state resistance. The device supports a wide VCC operating range from 2.3V to 3.6V, with data I/Os capable of signaling levels from 0.8V to 5V. It features 5-V tolerant I/Os, low input/output capacitance of 4 pF typical, and a fast switching frequency of 20 MHz maximum.

 

This bus switch is suitable for applications requiring efficient signal gating and isolation, such as PCI interfaces, differential signal interfaces, memory interleaving, and bus isolation. The SN74CB3Q3384APWR is supplied in a 24-TSSOP package suitable for surface mounting.

 

Additional features include low power consumption with a typical supply current of 1 mA, undershoot clamp diodes on data and control inputs, and support for partial-power-down mode operation. ESD performance is tested to 2000-V Human-Body Model and 1000-V Charged-Device Model.
