致新G2129 1-2-4-Bit Bidirectional Voltage-Level Translator with Automatic Direction Sensing and ±15kV ESD Protection
General Description
This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is de-signed to track VCCA. VCCAaccepts any supply volt-age from 1.2V to 3.6V. The B port is designed to track VCCB. VCCBaccepts 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. VCCAshould 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.
