HD74ALVCH16830

1-bit to 2-bit Address Driver with 3-state Outputs

ADE-205-196 (Z)

1st. Edition

February 2000

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, the output ebable (OE) input should be tied to VCC

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.

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
