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.
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)
