Core Capabilities Enabling Broad Adoption
The device's integrated diode to VCC enables level shifting from 5V inputs to 3.3V outputs, eliminating the need for external translators[
Its active undershoot protection circuitry on both A and B ports senses events down to –2V and keeps the switch in the proper state, preventing signal contention. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down, supporting partial-power-down system designs. With a typical on-state resistance of just 3Ω and near-zero propagation delay, the switch adds minimal signal degradation.
