N74F139N

The N74F139N is a kind of high speed, dual 1-of-4 decoder/demultiplexer. This N74F139N has two independent decoders, each accepting two binary weighted inputs (A0n, A1n) and providing four mutually exclusive active-Low outputs (Q0nQ3n). Each decoder has an active-Low Enable (E). When E is High, every output is forced High. The Enable can be used as the Data input for a 1-of-4 demultiplexer application.

There are some features of N74F139N as follows: (1)Demultiplexing capability; (2)Two independent 1-of-4 decoders; (3) Multifunction capability.

Then is about the absolute maximum ratings of N74F139N: (1)VCC, Supply voltage: 0.5 to +7.0 V; (2)VIN, Input voltage: 0.5 to +7.0 V; (3)IIN, Input current: 30 to +5 mA; (4)VOUT, Voltage applied to output in high output state: 0.5 to VCC V; (5)IOUT, Current applied to output in low output state: 40 mA; (6)Tamb, Operating free air temperature range: 0 to +70; (7)Tstg, Storage temperature range: 65 to +150.

The last one is about the recommended operating conditions of N74F139N: (1)VCC, Supply voltage: 4.5 V min, 5.0 V typ and 5.5 V max; (2)IIK, Input clamp current: 18 mA max; (3)iOH, High-level output current:-1 mA max; (4)IOL, Low-level output current: 20 mA max; (5)VIH, high level input voltage: 2.0 V min; (6)VIL, low level input voltage: 0.8 V max; (5)Tamb, Operating free-air temperature range: 0 to +70.
