This 1-bit to 2-bit address driver is designed for 1.65-V to 3.6-V VCC operation.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.

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.

  • Member of the Texas Instruments Widebus™ Family
  • Output Ports Have Equivalent 26- Series Resistors, So No External Resistors Are Required
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
  • Latch-Up Performance Exceeds 250 mA Per JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
    • 1000-V Charged-Device Model (C101)
