General Description

The FXL2SD106 is a configurable dual-voltage-supply translator designed for both uni-directional and bidirectional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCA level, and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V and 3.3V.

Features

■ Bi-directional interface between two levels from 1.1V to 3.6V

■ Fully configurable: Inputs and outputs track VCC level

■ Non-preferential power-up; either VCC may be powered-up first

■ Outputs remain in 3-state until active VCC level is reached

■ Outputs switch to 3-state if either VCC is at GND.

■ Power off protection

■ Bushold on data inputs eliminates the need for SDIO pull-up resistors

■ Control input (OE and CLK IN) are referenced to VCCA voltage

■ Packaged in 16-terminal DQFN (2.5mm x 3.5mm)

■ Direction control not needed

■ 80 Mbps throughput when translating between 1.8V and 2.5V

■ ESD protection exceeds:

– 12kV HBM (B port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7)

– 8kV HBM (A port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7)

– 1kV CDM (per ESD STM 5.3)
