SCES841E – JUNE 2012 – REVISED JUNE 2016 SN74AUP1T34 1-Bit Unidirectional Voltage-Level Translator
1 Features 3 Description 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. 1 Wide Operating VCC Range of 0.9 V to 3.6 V
Balanced Propagation Delays: tPLH = tPHL (1.8-V to
3.3-V Translation Typical)
Low Static-Power Consumption: Maximum of 5-ВµA
