24-Bit FET Bus Switch With Bus Hold
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.
