SN74AUP1T34DRYR

The SN74AUP1T34 device is a 1-bit noninverting
translator that uses two separate configurable powersupply rails. It is a uni-directional translator from A to
B. The A port is designed to track VCCA. VCCA accepts
supply voltages from 0.9 V to 3.6 V. The B port is
designed to track VCCB. VCCB accepts supply voltages
from 0.9 V to 3.6 V. This allows for low-voltage
translation between 1-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V,
and 3.3-V voltage nodes. The SN74AUP1T34 is also
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.
The VCC isolation feature ensures that if VCCA input
is at GND, the B port is in the high-impedance state.
If VCCB input is at GND, any input to the A side does
not cause the leakage current even floating.
