74LVC244A Octal Buffer/Driver
[SOIC 20]
€0.30

74LVC244A Octal Buffer/Driver with 3-state outputs

The SN74LVC244A is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. 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. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
Features:

  • Operates From 1.65 V to 3.6 V
  • Inputs Accept Voltages to 5.5 V
  • Product Number: SN74LVC244ADWRE4
  • DATASHEET.
