description

The

SN74CBT3245

provides

eight

bits

of

high-speed TTL-compatible bus switching in a

standard ’245 device pinout. The low on-state

resistance of the switch allows connections to be

made with minimal propagation delay.

The device is organized as one 8-bit 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 a high-impedance state exists between the two

ports.

The SN74CBT3245 is characterized for operation from – 40

°C to 85°C.
