SN74CBT3245APWR

LOGIC, 74CBT, X BAR SWITCH, TSSOP20.

The SN74CBT3245APWR is an octal FET Bus Switch provides eight 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 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 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 VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
