description/ordering information

The SN74CBTD16211 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. A diode to VCC is integrated in the circuit to

allow for level shifting from 5-V signals at the

device inputs to 3.3-V signals at the device

outputs.

The device is organized as a dual 12-bit bus

switch with separate output-enable (OE) inputs. It

can be used as two 12-bit bus switches or as one

24-bit bus switch. When OE is low, the associated

12-bit bus 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

ports.
