1-bit to 2-bit Address Driver with 3-state Outputs
ADE-205-197 (Z)
Preliminary
1st. Edition
November 1997
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 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. 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
