HD74LV244A - Octal Buffers / Drivers

General Description

The HD74LV244A has eight line drivers with three-state outputs in a 20-pin package.

Four non-inverters are included in one circuit.

Each circuit can be independently controlled by the enable signal 1OE or 2OE, which enables outputs when receiving a low-level signal.

Key Features

  • VCC = 2.0 V to 5.5 V operation.
  • All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V).
  • All outputs VO (Max. ) = 5.5 V (@VCC = 0 V).
  • Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
  • Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C).
  • Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V).
  • Ordering Information Part Name Package Type Package Code Package Abbreviation.

HD74LV244A Octal Buffers / Drivers with 3-state Outputs REJ03D0328–0300Z (Previous ADE-205-246A (Z)) Rev.3.00 Jun. 24, 2004 Description The HD74LV244A has eight line drivers with three-state outputs in a 20-pin package. Four non-inverters are included in one circuit. Each circuit can be independently controlled by the enable signal 1OE or 2OE, which enables outputs when receiving a low-level signal. Low-voltage operation is suitable for battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. Features • VCC = 2.0 V to 5.5 V operation • All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) • All outputs VO (Max.) = 5.5 V (@VCC = 0 V) • Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) • Typical VOH undershoot > 2.
