HD74LVC139 - Dual 2-to-4-line Decoders / Demultiplexers

General Description

The HD74LVC139 has two independent two-to-four-line decoders each with a single active low enable input in a 16 pin package.

Data on the select inputs cause one of the four normally high outputs to go low.

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) Function Table Input Enable G H L L L L H: L: X: Select B X L L H H High level Low level Immaterial A X L H L H Y0 H L H H H Y1 H H L H H Outputs Y2 H H H L H Y3 H H H H L HD74LVC139 Pin Arrangement 1G 1 1A.

HD74LVC139 Dual 2-to-4-line Decoders / Demultiplexers ADE-205-069B(Z) Rev.2 September 1995 Description The HD74LVC139 has two independent two-to-four-line decoders each with a single active low enable input in a 16 pin package. Data on the select inputs cause one of the four normally high outputs to go low. 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.
