Analog or Digital IC to Sequentially Switch 6V to 14 Relays on Momentary 2V Input

I am designing a rather simple PCB to control 14 component relay locks - I’m searching for a component/chip/digital/analog controller that will simply change direction of power each instance (mystery) component receives a momentary power input. So, let (mystery) component = X.
I have an alarm set twice per day. When it sends a 2VDC signal to X, it will send 6VDC across to lock 1. The SECOND 2VD input it receives will then channel 6VD across to lock 2 and so forth until lock 14 then reset to 1.

I have no idea what component can achieve this action, but if its analog it will be easier.

Many thanks!

Theree's no mystery component that does this, but you can design a logic circuit to do it. But I'm not clear on what you want to do.

You have a single 2VDC signal as an input, then youi want to use this to activate 6VDC signals to 14 Locks in sequence.

Do you want to send 6VDC to lock 1 on the first input, then remove that and send 6VDC to lock 2?
Or do you want to send 6VDC to lock 1, then to lock 2, etc till all 14 locks are activated?

There aere various ways to do this depending on which result you want. the number of locks (14) does complicate things (8 or 10 is easier) , but it's not impossible.

For activating only one lock at a time I'd use a binary 4-digit coiunter (Counts up to 16) and then decode it so a single state.

For activating the locks in sequence up to 14 all activated, I'd use a shift register that fills up with 1's.

Let us have more information and I can give you a more detailled answer. Cheeers // David

o achieve the desired functionality of changing the power direction to different locks based on input signals, you can consider using a digital or analog multiplexer (MUX) IC. A multiplexer allows you to select and route signals from multiple inputs to different outputs based on control signals.

Here's a suggestion for a possible approach using a digital multiplexer:

Choose a digital multiplexer IC with enough input channels to accommodate your 14 locks. Commonly used digital multiplexers include the 74HC4051 or CD4051, which have 8 channels.

Connect the 2VDC signal from your alarm system as one of the inputs to the multiplexer.

Connect the 6VDC power lines to the output channels of the multiplexer, which will be connected to the corresponding locks.

Connect the control inputs of the multiplexer to a binary counter or decoder circuit that will increment the control signal after each 2VDC signal received.

Configure the multiplexer to route the 2VDC signal to the appropriate lock's 6VDC power line based on the control signals.

By using a digital multiplexer in this way, you can control the direction of power to different locks based on the input signals you receive.

Alternatively, if you prefer an analog solution, you can explore analog multiplexers or switch ICs, such as the CD4052 or ADG708, which can perform similar signal routing functions in an analog domain.

Please note that the specific IC selection and circuit design may vary based on your specific requirements and constraints. It's always recommended to consult datasheets, reference designs, and possibly seek guidance from an experienced electronics engineer for your specific PCB design.
