Texas Instruments High-Performance Analog Signal Switches, Multiplexers, Decoders SN74CBT3345PWR

The SN74CBT3345PWR is an 8-bit FET bus switch designed for high-speed TTL-compatible bus switching. It features a standard ,Äô245 device pinout and provides a low on-state resistance, which minimizes propagation delay during operation. The device includes dual output-enable inputs (OE and OE), allowing for flexible control of the switch state. When either OE is low or OE is high, the switch connects port A to port B. Conversely, when OE is high and OE is low, the switch enters a high-impedance state, effectively disconnecting the two ports. This bus switch operates within a supply voltage range of 4.5V to 5.5V and is rated for an operating temperature range of -40¬8C to 85¬8C. The device is available in a TSSOP package, making it suitable for space-constrained applications. The typical on-state resistance is around 10 to 15 ohms at a supply voltage of 4.5V, and it has a propagation delay of approximately 0.25 ns, making it suitable for high-speed data applications.
