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 °C to +85 °C.


  • 5 Ω switch connection between two ports
  • TTL compatible control input levels
  • Designed to be used in 5.5 V to 3.3 V level shifting applications
  • Package options include shrink small outline (SSOP) and thin shrink small outline (TSSOP)
