Fairchild Semiconductor’s FXL2SD106 has a built-in automatic direction control allowing the device to sense and control the direction the data should flow, without a direction control pin.

This feature reduces design complexity by eliminating the need to program the General Purpose IO (GPIO) for direction control, and reduces the number of pins required for controlling the translator from 20 pins to 16 pins. It’s ideal for applications using SD cards such as printers, laptop PCs, GPS systems and camera phones.

It is packaged in 2.5mm x 3.5mm, 16-pin DQFN packaging. DQFN packaging features no signal pins in the centre of the package, allowing designers to easily bond this to the board. The FXL2SD106 has been specifically designed to protect SD cards from adverse ESD events. The portfolio includes the industry's first 4-bit, low voltage, dual supply voltage translator with independent-direction controls, the only single-bit, bi-directional voltage translator with guaranteed performance down to 1.1V and the first dual-supply, bi-directional translator with independent-direction controls.
