Texas Instruments SN74CB3T3245 8-Bit FET Bus Switches are high-speed, TTL-compatible switches with low ON-state resistance (RON) for minimal propagation delay. These bus switches support mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC. The SN74CB3T3245 bus switches feature a standard 245-type pinout, 5V-tolerant I/Os with device powered up or powered down, and output voltage translation tracks. Typical applications include level translation, PCI interface, USB interface, memory interleaving, and bus isolation.
