The SN74CBTH16211 provides 24 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 dual 12-bit bus switches with separate output-enable (OE\) inputs. It can be used as two 12-bit bus switches or one 24-bit bus switch. When OE\ is low, the associated 12-bit bus switch is on, and the A port is connected to the B port. When OE\ is high, the switch is open, and a high-impedance state exists between the two ports.

Active bus-hold circuitry is provided to hold unused or floating A and B ports at a valid logic level.

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.
