Description

This 20-bit universal bus driver is designed for 2.3 V to 3.6 V VCC operation.

Active bus hold circuitry is provided to hold unused or floating inputs at a valid logic level.

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 ±24 mA (@VCC = 3.0 V)

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