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 V CC 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 Ω 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.
