Product Summary
The 74AC139 is a high-speed, dual 1-of-4 decoder/demultiplexer. The 74AC139 has two independent decoders, each accepting two inputs and providing four mutually-exclusive active-LOW outputs. Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the 74AC139 can be used as a function generator providing all four minterms of two variables.
Parametrics
74AC139 absolute maximum ratings: (1)Supply Voltage (VCC): -0.5V to +7.0V; (2)DC Input Diode Current (IIK), VI= -0.5V: -20 mA; VI= VCC + 0.5V: +20 mA; (3)DC Input Voltage (VI): -0.5V to VCC + 0.5V; (4)DC Output Diode Current (IOK), VO = -0.5V: -20 mA; VO = VCC + 0.5V: +20 mA; (5)DC Output Voltage (VO): -0.5V to VCC + 0.5V; (6)DC Output Source or Sink Current (IO): ±50 mA; (7)DC VCC or Ground Current per Output Pin (ICC or IGND): ±50 mA; (8)Storage Temperature (TSTG): -65 to +150℃; (9)Junction Temperature (TJ): 140℃.
