HD74LVC138 - 3-to-8-line Decoder / Demultiplexer

General Description

The HD74LVC138 has three binary select inputs in a 16 pin package.

If the device is enabled these inputs determine which one of the eight normally high outputs will go low.

Two active low and one active high enables are provided to ease the cascading of decoders.

Key Features

  • VCC = 2.0 V to 5.5 V.
  • All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V).
  • 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).
  • Ordering Information Part Name Package Type Package Code HD74LVC138FPEL SOP.
  • 16 pin (JEITA) FP.
  • 16DAV HD74LVC138TELL TSSOP.

HD74LVC138 3-to-8-line Decoder / Demultiplexer REJ03D0349–0300Z (Previous ADE-205-068B (Z)) Rev.3.00 Jul. 23, 2004 Description The HD74LVC138 has three binary select inputs in a 16 pin package. If the device is enabled these inputs determine which one of the eight normally high outputs will go low. Two active low and one active high enables are provided to ease the cascading of decoders. 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.
