Voltage Level Translator Provides Direction-Free Flexibility for Networks and Servers

Diodes Incorporated released the PI4GTL2002 which is a new addition to its family of low voltage level translators. The PI4GTL2002 voltage level translator offers simple and autonomous bidirectional operation. The 2-bit level shifter is PI4GTL2002 is designed to translate signals conditioned for one voltage level to signals at a higher or lower voltage, such as gunner transceiver logic (GTL) or GTL+ to LVTTL/TTL.  The PI4GTL2002 meets the demand of high performance level translators with the added benefit of not imposing the need for directional control.


The PI4GTL2002 makes simpler PCB layout design with its convenient flow-through pin-out design. The device offers on-resistance of just 3.5Ω which minimizes signal distortion where as a low input and output capacitance keeps the propagation delay low. The PI4GTL2002 offers voltage translation between signals ranging from 0.8V to 5V with the help of a common gate to enable bidirectional operation and reference voltages for each of the two signals. This helps the design team to apply a different voltage to either side of the device.


The open-drain design of the PI4GTL2002 allow it to translate voltage levels in either direction without incurring the design complexity or performance penalty of a dedicated direction control signal. The direction operation shift between 0.8V and 5V (CMOS) happens in less than 1.5ns propagation delay between inputs and outputs. Including standard and fast mode I2C, the PI4GTL2002 can support a number of use cases.


The PI4GTL2002UEX is available in the U-QFN package, the PI4GTL2002WEX W-QFN package, and the PI4GTL2002XTEX in the XT-QFN package at Diodes website.
