讯号标准不断推陈出新，而电位也持续降低。由于许多产品皆具备双向功能，并可从 1-bit 扩充至 +32-bit，同时支持 1.5 V 至 5 V 通讯电源，现今的设计工程师发现到，自己定期在寻求解决方案来解决这些混合产品应用之间的通讯问题。Diodes 生产各种可提供混合讯号（TTL、HSTL 及 SSTL）和多重供应电压（5 V、3.3 V、2.5 V、1.8 V 及 1.2 V）的转换 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.
