3 Description
This 8-bit non-inverting translator uses two separate
configurable power-supply rails. The A port tracks the
V_CCA pin supply voltage. The V_CCA pin accepts any
supply voltage between 1.4 V and 3.6 V. The B port
tracks the V_CCB pin supply voltage. The V_CCB pin
accepts any supply voltage between 1.65 V and 5.5
V. Two input supply pins allows for low Voltage
bidirectional translation between any of the 1.5 V, 1.8
V, 2.5 V, 3.3 V, and 5 V voltage nodes.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance (Hi-Z) state.
To ensure the Hi-Z state during power-up or power-
down periods, tie OE to GND through a pull-down
resistor. The minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
