CBTD16210 20-bit Level Shifting Bus Switch With 10-bit Output Enables

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 Cel to +85 Cel.
