Description

This 1-bit to 2-bit address driver is designed for 2.3 V to 3.6 V VCC operation. To ensure the high impedance state during power up or power down, OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current sinking capability of the driver. Active bus hold circuitry is provided to hold unused or floating inputs at a valid logic level. All outputs, which are designed to sink up to 12 mA, include equivalent 26 ? resistors to reduce overshoot and undreshoot.

Features

? VCC = 2.3 V to 3.6 V

? Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

? Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

? High output current ±12 mA (@VCC = 3.0 V)

? Bus hold on data inputs eliminates the need for external pullup / pulldown resistors

? All outputs have equivalent 26 ? series resistors, so no external resistors are required
