MC74LVX139
Dual 2-to-4 Decoder/
Demultiplexer
The MC74LVX139 is an advanced high speed CMOS 2–to–4
decoder/ demultiplexer fabricated with silicon gate CMOS technology.
When the device is enabled (E = low), it can be used for gating or as
a data input for demultiplexing operations. When the enable input is
held high, all four outputs are fixed high, independent of other inputs.
The inputs tolerate voltages up to 7 V, allowing the interface of 5 V
systems to 3 V systems.
• High Speed: tPD = 6.0 ns (Typ) at VCC = 3.3 V
• Low Power Dissipation: ICC = 4 µΑ (Max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2 V to 3.6 V Operating Range
• Low Noise: VOLP = 0.5 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance: HBM > 2000 V; Machine Model > 200 V
• Chip Complexity: 100 FETs or 25 Equivalent Gates
