The DIODES™ LXS0104 is a 4-bit configurable, dual-supply, bidirectional, auto-sensing translator that does not require a directional control pin. The A and B ports are designed to track two different power supply rails, VCCA and VCCB respectively. This allows bidirectional translation between lower and higher logic signal levels.

When the OE pin is low, all I/O are configured to be in a high-impedance state.

Power-off protection is implemented to prevent current passing through the device when it is powered-down.
