3 Description
The SN74AUP1T34-Q1 device is a 1-bit noninverting
translator that uses two separate configurable power-
supply rails. It is a unidirectional translator from A to
B. The A port is designed to track V_CCA. V_CCA accepts
supply voltages from 0.9 V to 3.6 V. The B port is
designed to track V_CCB. V_CCB 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-Q1 is
also fully specified for partial-power-down
applications using I_off. The I_off circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.
The VCC isolation feature ensures that if V_CCA input
is at GND, the B port is in the high-impedance state.
If V_CCB input is at GND, any input to the A side does
not cause the leakage current even floating.
