SY100ELT28K数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The SY10/100ELT28 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 +5V and ground are required. The small outline 8-pin package and the dual translation design of the ELT28 makes it ideal for applications which are sending and receiving signals across a backplane.
