IDT74CBTLV6800
DESCRIPTION:
The CBTLV6800 provides 10-bits of high-speed bus switching with low on-state resistance of the switch allowing connections to be made with minimal propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise. The CBTLV6800 is organized as a single 10-bit bus switch with a single output-enable (OE) input. When OE is low, the 10-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, and port B is precharged to BIASV through the equivalent of a 10-kΩ resistor. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
