Product details

Single 2:4 decoder in a tiny 8-pin package

The SN74LVC1G139DCUR: The 32 mA output drive per channel is enough to directly sink a small relay or a bank of LEDs without a buffer stage.

Supply range and temperature — fits industrial panels

The 1.65 V minimum supply means it can work alongside newer low-voltage MCUs (1.8 V core) while still tolerating legacy 5 V logic on the same rail. No level-shifter needed between a 3.3 V FPGA and a 5 V peripheral — the decoder sits right in the middle.

The 74LVC series is a mature logic family, and the SN74LVC1G139DCUR is a standard catalog item with no exotic process or package.

Frequently asked questions

What is the function of SN74LVC1G139?

It is a single 2:4 decoder/demultiplexer — you feed a 2-bit binary address on the select inputs, and the corresponding output (one of four) goes active low. The other three outputs stay high. This is the standard 74x139 function in a single-gate package.
