Try something like below in your observer file.

<?php

namespace Custom\Module\Observer;

use Magento\Framework\Event\ObserverInterface;

class SalableObserver implements ObserverInterface
{
    ...

    protected $dataHelper;

    ...

    public function __construct(
        ...
        \Custom\Module\Helper\Data $dataHelper
        ...
    ) {
        ...
        $this->dataHelper = $dataHelper;
        ...
    }

    public function ...(){
        $helper = $this->dataHelper;
    }

    ...
}

?>
