The 74VHC139MTCX is a dual 2-to-4 line decoder/demultiplexer integrated circuit. It comes in a 16-pin TSSOP package. Each of the two decoder sections has two inputs, A and B, and an active-low enable input, \(\overline{\text{G}}\). The outputs for each section are four lines, Y0 to Y3, which are active-low.
Pin configuration is generally as follows:
1. \(\overline{\text{G1}}\) - Enable input for decoder 1
2. A1 - Address input for decoder 1
3. B1 - Address input for decoder 1
4. Y0_1 - Output 0 for decoder 1
5. Y1_1 - Output 1 for decoder 1
6. Y2_1 - Output 2 for decoder 1
7. Y3_1 - Output 3 for decoder 1
8. GND - Ground
9. Y3_2 - Output 3 for decoder 2
10. Y2_2 - Output 2 for decoder 2
11. Y1_2 - Output 1 for decoder 2
12. Y0_2 - Output 0 for decoder 2
13. B2 - Address input for decoder 2
14. A2 - Address input for decoder 2
15. \(\overline{\text{G2}}\) - Enable input for decoder 2
16. VCC - Positive supply voltage
Each decoder operates independently, selecting one of its four output lines based on the binary value of the address inputs, only when the enable input is low.
