Descriptions
DIO74134 is a 1-bit level conversion device with
two independent configurable power rails. As a
uni-directional translator from A to B, the A port is
designed to track VCCA, and the B port is designed
to track VCCB. Both VCCA and VCCB accept a power
supply voltage of 1.08V to 3.6V. This allows for
low-voltage translation between 1.08V, 1.2V, 1.5V,
1.8V, 2.5V, and 3.3V Voltage nodes. Also DIO74134
is fully designated for partial power-off
applications using Ioff. The Ioff circuit disables the
output, preventing destructive current flow back
when the device is powered off.
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 will not cause the leakage
current even floating.
