CBT3245ABQ

Octal bus switch

The CBT3245A provides eight bits of high-speed TTL-compatible bus switching. The low ON resistance of the switch allows connections to be made with minimal propagation delay.

The CBT3245A is organized as one 8-bit bus switches with one output enable (OE) input. When OE is LOW, the switch is on and port A is connected to the B port. When OE is HIGH, each switch is disabled. The CBT3245A is characterized for operation from -40 °C to +85 °C.

Features

  • 5 Ω switch connection between two ports
