description/ordering information

The SN74CBTD16210 provides 20 bits of

high-speed TTL-compatible bus switching. The

low on-state resistance of the switch allows

connections to be made with minimal propagation

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 10-bit bus

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

can be used as two 10-bit bus switches or as one

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

10-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.
