Overview
The SN74CBTLV3383DBQR, produced by Texas Instruments, is a low-voltage 10-bit FET bus-exchange switch. This device is designed to provide high-speed bus switching or exchanging, with the capability to operate as either a 10-bit bus switch or a 5-bit bus exchanger. The low on-state resistance of the switch allows connections to be made with minimal propagation delay, making it suitable for applications requiring fast and reliable signal switching.
