description

The SN74CBTLV3245 provides eight bits of

high-speed 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.

NC – No internal connection

The device is organized as one 8-bit switch. When output enable (OE) is low, the 8-bit bus 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.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74CBTLV3245 is characterized for operation from –40°C to 85°C.
