General Description
This 4-bit noninverting translator uses two separate
configurable power-supply rails. The A port is de-
signed to track VCCA. VCCA accepts any supply volt-
age from 1.2V to 3.6V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
1.65V to 5.5V. This allows for universal low-voltage
bidirectional translation between any of the 1.2V,
1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. VCCA
should not exceed VCCB.
When the enable-output (EO) input is low, all
outputs are placed in the high-impedance state.
To ensure the high-impedance state during power
up or power down, EO should be tied to GND
through a pulldown resistor; the minimum value of
the resistor is determined by the current-sourcing
capability of the driver.
The G2129 is designed so that the EO input circuit is
supplied by VCCA.
This device is 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.
