SN74CBT3306PWRG4 Description

Short technical summary and product information.

The Texas Instruments SN74CBT3306PWRG4 is a dual FET bus switch designed for 5V digital signal routing. It features two independent single-pole single-throw (SPST) switches, each controlled by a dedicated output-enable input. The device supports TTL-compatible input levels and operates from a single 4.5V to 5.5V supply.

 

The switches provide low ON-state resistance for minimal signal distortion. The SN74CBT3306 is ideal for bus isolation, signal multiplexing, and general-purpose switching in digital systems. Each switch is disabled when its output-enable input is high.

 

The device is housed in a surface-mount TSSOP-8 package (PW code) measuring 0.173 inches (4.40mm) wide. It supports an operating temperature range of -40°C to 85°C, making it suitable for industrial environments. The part is now obsolete; Texas Instruments recommends the SN74CBT3306CPWR as a pin-compatible replacement with added undershoot protection.
