description
The SN74CBTLV3245A 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.
The device is organized as one 8-bit switch. When output enable (OE) is low, the 8-bit bus switch is on and A port
is connected to B port. When OE is high, the switch is open and the 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
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74CBTLV3245A is characterized for operation from –40
°
C to 85
°
C.
