Diodes Incorporated (Nasdaq: DIOD) today announced a new addition to its
family of low voltage level translators, offering simple and autonomous
bidirectional operation. The PI4GTL2002 is a 2-bit level shifter
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. As leading processor manufacturers continue
to include GTL+ interfaces in their products, the need for high
performance level translators is increasing in applications such as
server/data centers and networking. The PI4GTL2002 meets that demand
with the added benefit of not imposing the need for directional control.
The open-drain design of the PI4GTL2002 means the device can translate
voltage levels in either direction without incurring the design
complexity or performance penalty of a dedicated direction control
signal. The device operates in either direction, shifting between 0.8V
and 5V (CMOS), with less than 1.5ns propagation delay between inputs and
outputs. As such, the PI4GTL2002 can support a number of use cases,
including standard and fast mode I2C.
The NMOS-based pass transistors in the design use a common gate to
enable bidirectional operation, with reference voltages for each of the
two signals. This enables the design team to apply a different voltage
to either side of the device, allowing voltage translation between
signals ranging from 0.8V to 5V.
The pin-out of the PI4GTL2002 follows a convenient flow-through design,
making PCB layout simpler. A low input and output capacitance keeps the
propagation delay low, while the device also features an on-resistance
of just 3.5Ω to minimize signal distortion.
The PI4GTL2002UEX is available in the U-QFN package, the PI4GTL2002WEX
W-QFN package, and the PI4GTL2002XTEX in the XT-QFN package. Further
