† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.

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 between 5-V inputs and 3.3-V outputs.

The SN74CBTD16211 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 A port is connected to B port. When OE is high, the switch is open, and a high-impedance state exists between the ports.

The SN74CBTD16211 is characterized for operation from 40°C to 85°C.
