lingxingic · Signal Switches, Multiplexers, Decoders · DIP-16

SN74HC139N from lingxingic, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1E input Active-LOW enable input for decoder 1; when HIGH, all decoder 1 outputs are forced HIGH, and it can serve as the data input for a 1-to-4 demultiplexer.
2 1A0 input Address input 0 for decoder 1, one of two binary-weighted address inputs that select which output goes LOW.
3 1A1 input Address input 1 for decoder 1, one of two binary-weighted address inputs that select which output goes LOW.
4 1Y̅0 output Active-LOW mutually exclusive output 0 of decoder 1.
5 1Y̅1 output Active-LOW mutually exclusive output 1 of decoder 1.
6 1Y̅2 output Active-LOW mutually exclusive output 2 of decoder 1.
7 1Y̅3 output Active-LOW mutually exclusive output 3 of decoder 1.
8 GND power_in Ground (0 V) reference for the device.
9 2Y̅3 output Active-LOW mutually exclusive output 3 of decoder 2.
10 2Y̅2 output Active-LOW mutually exclusive output 2 of decoder 2.
11 2Y̅1 output Active-LOW mutually exclusive output 1 of decoder 2.
12 2Y̅0 output Active-LOW mutually exclusive output 0 of decoder 2.
13 2A1 input Address input 1 for decoder 2, one of two binary-weighted address inputs that select which output goes LOW.
14 2A0 input Address input 0 for decoder 2, one of two binary-weighted address inputs that select which output goes LOW.
15 2E input Active-LOW enable input for decoder 2; when HIGH, all decoder 2 outputs are forced HIGH, and it can serve as the data input for a 1-to-4 demultiplexer.
16 VCC power_in Supply voltage; the datasheet recommends 2.0 V to 6.0 V (typ. 5.0 V) for SN74HC139 and 4.5 V to 5.5 V for SN74HCT139.
