SN74CB3Q3306APWR Description

Short technical summary and product information.

The SN74CB3Q3306APWR from Texas Instruments is a 2-channel, 1:1 SPST FET bus switch designed for high-speed signal routing. It features a high bandwidth of up to 500 MHz, making it suitable for demanding applications.

 

The device supports a wide input/output voltage range from 0 V to 5.5 V and operates with a VCC supply range of 2.3 V to 3.6 V. It offers low and flat ON-state resistance, typically 4 Ω, minimizing signal distortion. The switch has a typical OFF-state leakage current of 1 µA and low output capacitance.

 

Designed for surface mounting, the SN74CB3Q3306APWR comes in an 8-TSSOP package. Its operating temperature range is -40°C to 85°C. The switch supports bidirectional data flow with near-zero propagation delay and is suitable for both digital and analog applications, including USB interfaces and bus isolation.

 

Key electrical characteristics include a typical supply current of 700 µA and ESD protection tested to 2000 V (HBM) and 1000 V (CDM). The control inputs are TTL and 5-V/3.3-V CMOS compatible.
