CJMCU-0102 TXS0102 2-bit bidirectional voltage level shifter I2C IIC-level modules This
two-bit non-inverting translator is a bidirectional voltage-level
translator and can be used to establish digital switching compatibility
between mixed-voltage systems. It uses two separate configurable
power-supply rails, with the A ports supporting operating voltages from
1.65 V to 3.6 V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply.
This allows the support of both lower and higher logic signal levels
while providing bidirectional translation capabilities between any of
the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. When
the output-enable (OE) input is low, all I/Os are placed in the
high-impedance state, which significantly reduces the power-supply
quiescent current consumption. To
ensure the high-impedance state during power up or power down, OE
should be tied to GND through a pulldown resistor; the minimum value of
the resistor is determined by the current-sourcing capability of the
driver. |
