訊號標準不斷推陳出新，而電位也持續降低。由於許多產品皆具備雙向功能，並可從 1-bit 擴充至 +32-bit，同時支援 1.5 V 至 5 V 通訊電源，現今的設計工程師發現到，自己定期在尋求解決方案來解決這些混合產品應用之間的通訊問題。Diodes 生產各種可提供混合訊號（TTL、HSTL 及 SSTL）和多重供應電壓轉換（5 V、3.3 V、2.5 V、1.8 V 及 1.2 V） 的IC。
Level Shifting
Pericom offers great chip-to-chip interface between different I/O voltages ranging from 1.5/1.8/2.5/3.3 V to 5 V, and 0.8 V to 2.5 V. These translators are scalable from 16-bit to 32-bits and beyond. See following page for product listing.
I/O Signal Translation
These devices provide the ability to convert between different I/O’s (HSTL to LVTTL or LVCMOS, SSTL to TTL, etc.) and are scalable from 12-bit to 32-bit and beyond.
