Description
This 4-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is designed
to track VCCA. VCCA accepts any supply voltage from
1.2V to 3.6V. The B port is designed to track VCCB. VCCB
accepts any supply voltage from 1.65V to 5.5V. This
allows for universal low-voltage bidirectional translation
between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and
5V voltage nodes. VCCA should not exceed VCCB.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state.
The PI4ULS5V104 is designed so that the OE input
circuit is supplied by VCCA.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow through
the device when it is powered down.
To ensure the high-impedance state during power up or
power down, OE should be tied to GND through a pull-
down resistor; the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
