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 SN74CBTH16211 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.
SN74CBTH16211 Active bus-hold circuitry is provided to hold unused or floating A and B ports at a valid logic level.
To ensure the SN74CBTH16211 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.
The SN74CBTH16211 is characterized for operation from 40°C to 85°C.
