Voltage ranges and channel count — fit for mixed-voltage buses
VCCA accepts 1 V to 3.6 V;
Auto-direction sensing — one less GPIO to manage
The auto-direction sensing feature monitors each channel's voltage transition and switches the pass-gate direction accordingly. No DIR pin means one fewer GPIO on the host controller and simpler PCB routing. The translator handles open-drain outputs (for I²C, SMBus) and push-pull outputs (for SPI, UART, general-purpose GPIO) without external pull-up resistors on the push-pull lines — though open-drain lines still need pull-ups to the respective supply rail.
ROHS3 compliant. No last-time-buy notice or end-of-life window is on record.
