1-bit to 2-bit Address Driver with 3-state Outputs
REJ03D0040-0200Z (Previous ADE-205-197(Z)) Rev.2.00 Oct.02.2003
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 = 25C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25C) 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

Notes: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to e the device. These are stress ratings only, and functional operation of the device at these or any unctional other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 1. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The maximum package power dissipation is calculated using a junction temperature of 150C and a board trace length of 750 mils.
