SN74LVTH244AZQNR Products

These octal buffers and line drivers are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The ’LVTH244A devices are organized as two 4-bit line drivers with separate output-enable (OE)\ inputs. When OE\ is low, the devices pass data from the A inputs to the Y outputs. When OE\ is high, the outputs are in the high-impedance state.

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 data inputs at a valid logic level. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.

Feature

  • Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC)
  • Typical VOLP (Output Ground Bounce)    <0.8 V at VCC = 3.3 V, TA = 25°C
  • Support Unregulated Battery Operation Down to 2.7 V
  • Ioff and Power-Up 3-State Support Hot Insertion
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
  • Latch-Up Performance Exceeds 500 mA Per JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
