description/ordering information
The SN74CBT32245 provides 32 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.
The device is organized as four 8-bit bus switches, two 16-bit bus switches, or one 32-bit bus switch. When output enable (OE) is low, the switch is on and port A is connected to port B. When OE is high, the switch is open and the high-impedance state exists between the two ports.
