Vat-debit note- claim of input tax credit available?

Dear all,

While paying VAT, can we avail claim of input tax credit based on debit note raised by seller of goods?

The situation is, due to hike in prices of goods, the seller has issued debit note in lieu of Tax invoice for the increased price (as per agreed terms and conditions) to the purchaser. My doubt is whether the debit note can be treated at par with Tax invoice while claiming the input tax credit? 

Regards.
