Remote control using CD4532

[bobyx]

Hello everybody,
I designed a 6-channel remote control to control 6 devices
and used a PT2272-M6,a CD4050 ,a CD4532 and a L293D to control
2 dc motors; move right,left, forward and revers : thery are 4 channels.
As you see in my RCCX.SchDoc.png attachment, I connected the Q0,Q1 and Q2 pins
of CD4532 into inputs,IN1,IN2,IN3 and IN4 of the motor driver L293D.
It works good and correctly.
But,I want to control 2 more channels and I do not know how to
connect Q0,Q1 and Q2 lines for those 2 more channels;the 2 relays K1
and K2 circuit drivers,,so that I can control them separately and
individually??
Would you please help me for that?

Thanks,
bobyx

You have already used your 3 binary-coded outputs as single outputs, so with that circuit you can't. What you would need is a way to decode six of the eight 3-binary output bytes as six single outputs. This might be done with two triple 3-input AND gate chips. That would allow six outputs for 6 of the 8 inputs. Not sure if any of the outputs to the motors and relays have to occur simultaneously.
