 DESCRIPTION
The UNTB0102 is a 2-bit, dual supply translating transceiver
with auto direction sensing, that enables bidirectional voltage level
translation. It features two 2-bit input-output ports (An and Bn), one
output enable input (OE) and two supply pins (VCCA and VCCB).
VCCA can be supplied at any voltage between 1.2V and 3.6V and
VCCB can be supplied at any voltage between 1.65V and 5.5V,
making the device suitable for translating between any of the low
voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V).
Pins An and OE are referenced to VCCA and pins Bn are
referenced to VCCB. A LOW level at pin OE causes the outputs to
assume a high-impedance OFF-state. This device is fully specified
for partial power-down applications using IOFF. The IOFF circuitry
disables the output, preventing the damaging backflow current
through the device when it is powered down.
