MC10ELT28屬于集成電路（IC）的轉換器電平移位器。由安森美半導體公司制造生產的MC10ELT28轉換器，電平移位器邏輯轉換器或電平移位器 IC 可用于在數字邏輯設備之間傳遞信息，這些設備可在不同/不兼容的供電電壓下工作，或可實現不同的信令方式。例如，可以將需要 5 V 電源的數字輸出傳感器連接到具有 3.3 V I/O 電源的 FPGA，或者在 CMOS 或 TTL 等單端信令方式與 PECL 或 LVDS 等差分技術之間進行轉換。

描述 Description

The MC10ELT/100ELT28 is a differential PECL to TTL translator and a TTL to differential PECL translator in a single package. Because PECL (Positive ECL) levels are used, only +5 V and ground are required. The small outline 8-lead package and the dual translation design of the ELT28 makes it ideal for applications which are sending and receiving signals across a backplane.

The 100 Series contains temperature compensation.
