HD74LVC244A - Octal Buffers / Line Drivers

Description

The HD74LVC244A has eight line drivers with three state outputs in a 20 pin package.

This device is a non inverting buffer and has two active low enables (1G and 2G).

Each enable independently controls four buffers.

Features

  • VCC = 2.0 V to 5.5 V All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max. ) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs G H L L H: L: X: Z: High level Low level Immaterial High impedance A X H L Output Y Z H L HD74LVC244A Pin Arra.

This device is a non inverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features • • • • • • VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.
