PI4ULS5V102 2-Bit Universal Bi-directional Level Shifter with Automatic Direction Control & Advance Package Solution Features Description This 2-bit non-inverting translator uses two separate 1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port configurable power-supply rails. The A port is designed (V V ) CCA CCB to track V . V accepts any supply voltage from V Isolation Feature If Either V Input Is at CCA CCA CC CC 1.2V to 3.6V. The B port is designed to track V . V GND, All Outputs Are in the High-Impedance State CCB CCB accepts any supply voltage from 1.65V to 5.5V. This OE Input Circuit Referenced to V CCA allows for universal low-voltage bidirectional translation Low Power Consumption, 5 A Max I CC between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and I Supports Partial-Power-Down Mode Operation off 5V voltage nodes. V should not exceed V . CCA CCB Latch-Up Performance Exceeds 100mA Per JESD 78, Class II When the output-enable (OE) input is low, all outputs ESD Protection Exceeds JESD 22 are placed in the high-impedance state. A Port This device is fully specified for partial-power-down 2500-V Human-Body Model (A114-F) applications using I . The I circuitry disables the off off 200-V Machine Model (A115-A) outputs, preventing damaging current backflow through 1500-V Charged-Device Model (C101D) the device when it is powered down. B Port To ensure the high-impedance state during power up or 15-kV Human-Body Model (A114-F) 200-V Machine Model (A115-A) power down, OE should be tied to GND through a pull- 1500-V Charged-Device Model (C101D) down resistor the minimum value of the resistor is determined by the current-sourcing capability of the driver.
