SN74CBT3305CD [Texas Instruments]

The SN74CBT3305C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r_on), allowing for minimal propagation delay. It features active undershoot-protection circuitry on the A and B ports for protection up to –2 V. The device is organized as two 1-bit bus switches with separate output-enable inputs, supporting bidirectional data flow, low power consumption, and partial-power-down mode operation. It supports both digital and analog applications such as USB interface, bus isolation, and low-distortion signal gating.
