General-purpose level shifter
In addition to the dedicated I²C level shifters, the board also makes available a single-channel,
tristatable, unidirectional level shifter that is not connected to any signals by default. Four pins are
exposed:
OE
(output enable),
IN
(input),
OUT
(shifted output), and
VCC
(logic supply voltage).
• When OE is high, OUT is in a high impedance state.
• When OE is low, OUT matches the state of
IN
, shifted to the voltage supplied on VCC.
