3 Description

This device is an 8-bit non-inverting level translator

which uses two separate configurable power-supply

rails. The A port tracks the VCCA pin supply voltage.

The VCCA pin accepts any supply voltage between

1.4V and 3.6V. The B port tracks the VCCB pin

supply voltage. The VCCB pin accepts any supply

voltage between 1.65V and 5.5V. Two input supply

pins allows for low Voltage bidirectional translation

between any of the 1.5V, 1.8V, 2.5V, 3.3V, and 5V

voltage nodes.

When the output-enable (OE) input is low, all outputs

are placed in the high-impedance (Hi-Z) state.

To put the device in the Hi-Z state during power-up

or power-down periods, tie OE to GND through a pulldown

resistor. The current-sourcing capability of the

driver determines the minimum value of the resistor.
