HD74LVC139

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) 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 1B 2 3 A B Y0 Y1 Y2 Y3 G G A B Y0 Y1 Y2 Y3 16 VCC 15 2G 14 2A 13 2B 12 2Y0 11 2Y1 10 2Y2 9 2Y3 1Y0 4 1Y1 5 1Y2 6 1Y3 7 GND 8 (Top view) Absolute Maximum Ratings Item Supply voltage Input diode current Input voltage Output diode current Symbol VCC I IK VI I OK Ratings –0.5 to 6.0 –50 –0.5 to 6.0 –50 50 Output voltage Output current VCC, GND current / pin Storage temperature VO IO I CC or IGND Tstg ±50 100 –65 to 150 Unit V mA V mA mA VO = –0.5 V VO = VCC +0.5 V VI = –0.5 V Conditions –0.5 to VCC +0.5 V mA mA °C Note: Th...
