These devices feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. To ensure the high-impedance state during power up or power down, tie OE to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 9.2 Functional Block Diagram Figure 4. Logic Diagram (Positive Logic) 9.3 Feature Description • Wide operating voltage range – Operates from 2 V to 5.5 V • Allows down-voltage translation – Inputs accept voltages to 5.5 V • Ioff Feature – Supports Live Insertion, Partial Power-Down Mode, and Back-Drive Protection 9.4 Device Functional Modes Table 1.
