Legacy Products

Highland is committed to providing long-term availability of products and product support. The following products are not recommended for new design due to difficulty stocking components and high component costs. Highland will continue to support existing customers by producing and maintaining these designs whenever possible. New customers are encouraged to consider replacement products, listed below each legacy product.
