G2129 Global Mixed-mode Technology 1-2-4-Bit Bidirectional Voltage-Level Translator with Automatic Direction Sensing and ±15kV ESD Protection Features General Description 1.2V to 3.6V on A port and 1.65V to 5.5V on B port (VCCA ≤ VCCB) VCC Isolation Feature-If Either V Input Is at This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage 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. CC GND, All Outputs Are in the High-Impedance State EO Input Circuit Referenced to VCCA Low Power Consumption, 5µA Max ICC No Power-Supply Sequencing Required-Either VCCA or VCCB Can be Ramped First Ioff Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 100mA Per JESD 78, Class II ESD Protection Exceeds JESD 22 – A Port 2500V Human-Body Model (A114-B) 1500V Charged-Device Model (C101) – B Port ±15kV Human-Body Model (A114-B) 1500V Charged-Device Model (C101) SC-70-6 (SOT-363), SOT-23-6, SOT-23-8, AQFN1.7X2.0-12 and AQFN1.5X1.5-8 Package 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.
