Overview
The SN74CBTD3384PWR, manufactured by Texas Instruments, is a 5-V, 1:1 (SPST), 10-channel general-purpose FET bus switch. This device is designed to provide high-speed TTL-compatible bus switching and is particularly useful in level-shifting applications between 5-V inputs and 3.3-V outputs. It features two 5-bit switches with separate output-enable (OE) inputs, allowing for flexible control over the switch states. The low on-state resistance of the switches ensures minimal propagation delay, making it suitable for high-speed applications.
