5-Ω Switch Connection Between Two Ports

TTL-Compatible Input Levels

Designed to Be Used in Level-Shifting

Applications

description/ordering information

The ’CBTD3384 devices provide ten bits of high-speed TTL-compatible bus switching. The low on-state

resistance of the switches allows connections to be made without adding propagation delay. A diode to VCC is

integrated on the die to allow for level shifting from 5-V signals at the device inputs to 3.3-V signals at the device

outputs.

These devices are organized as two 5-bit switches with separate output-enable (OE) inputs. When OE is low,

the 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 two ports.
