LXS0108

Description

The LXS0108 is an 8-bit, dual-supply, automatic direction sensing level translator. The A and B ports are designed to track two different power supply rails, VCCA and VCCB respectively. This allows bi-directional translation between lower and higher logic signals. Each channel can be mixed and matched with different output types (open-drain or push-pull) and mixed data flows (transmit or receive) without intervention from the host.

When the OE pin is low, all I/Os are configurated to be in a high-impedance state. To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through a pull-down resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

The LXS0108 is available in the TSSOP-20 and W-QFN3545 package with temperature range specified from -40°C to +85°C.
