SN74CB3Q3305PWR Description

Short technical summary and product information.

The SN74CB3Q3305PWR from Texas Instruments is a 2-channel, 1:1 (SPST) FET bus switch designed for low-voltage applications. It supports a wide operating voltage range of 2.3V to 3.6V, making it suitable for various system designs.

 

This bus switch offers a high-bandwidth data path up to 500 MHz and features low ON-state resistance of 3 Ω typical. It supports bidirectional data flow with near-zero propagation delay and low input/output capacitance, minimizing signal distortion. The device operates over a temperature range of -40°C to 85°C and is available in an 8-TSSOP package.

 

Key electrical characteristics include 5-V tolerant I/Os, support for 0 to 5 V switching with 3.3 V VCC, and low power consumption. The control inputs can be driven by TTL or 5V/3.3V CMOS outputs. Latch-up performance exceeds 100 mA per JESD 78, Class II.

 

Designed for surface mount, the SN74CB3Q3305PWR is packaged in an 8-TSSOP with a package quantity of 2000 units on a large tape and reel.
