Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SN74CB3Q3245GQNR

The SN74CB3Q3245GQNR is a high-bandwidth FET bus switch designed for efficient data routing in digital applications. It supports a wide operating voltage range from 2.3 V to 3.6 V and is compatible with 0- to 5-V signaling levels, making it versatile for various interfacing needs. The device features low ON-state resistance (ron) of approximately 5 ,Ѷ, which minimizes propagation delay and signal distortion, ensuring reliable performance in high-speed applications. This bus switch is organized as four 8-bit switches, allowing flexible configurations as four 8-bit, two 16-bit, or one 32-bit switch. It provides bidirectional data flow with near-zero propagation delay and low input/output capacitance, which is crucial for maintaining signal integrity. The device also includes features for partial-power-down operation, ensuring low power consumption and preventing backflow current when powered down. With a maximum switching frequency of 20 MHz and robust ESD protection, the SN74CB3Q3245GQNR is suitable for applications in broadband communications, networking, and data-intensive computing systems. Its compact LFBGA package facilitates integration into space-constrained designs.
