Rangkaian gerbang logika EX-NOR pengganti, ditunjukkan pada gambar di bawah ini


Y = (A.B) + (A.B)

Ingat, sifat EX-NOR yaitu apabila inputnya berlogik sama, maka akan menghasilkan output 1, dan bila inputnya berlainan, akan menghasilkan output 0.

Elektronika Bersama. Simulasi EX-NOR gate atau mengetes rangkaian gerbang logik EX-NOR (IC 74266) menggunakan bantuan software aplikasi Electronics Workbench.

Input
0 = dihubungkan ke GND (0V)
1 = dihubungkan ke +VCC (5 VDC).

Output
0 = lampu led padam
1 = lampu led menyala.
Led diseri dengan resistor 330 Ω, menjaga agar arus yang mengalir ke led sebesar 15 mA.
