DESCRIPTION

The CBTD16210 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 delay.

A diode to VCC is integrated in the circuit to allow for level shifting

between 5 V inputs and 3.3 V 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 a high-impedance state exists between

the ports.

The CBTD16210 is characterized for operation from –40°C to

+85°C.
