SY100EPT28L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 SY10/100EPT28L is a differential LVPECL-to- LVTTL translator and a LVTTL-to-differential LVPECL translator in a single package. Because LVPECL (Positive ECL) levels are used, only +3.3V and ground are required. The small outline 8-pin package and the dual translation design of the EPT28L makes it ideal for applications which are sending and receiving signals across a backplane. The 100k series includes temperature compensation. Thus, logic levels are constant over temperature.

·<600ps LVTTL-to-LVPECL propagation delay
·Internal 75kΩ input pull-down resistors
·Industrial temperature range: –40°C to +85°C
·Available in 8-pin MSOP and SOIC packages

简介

SY100EPT28L属于集成电路（IC）的转换器电平移位器。由制造生产的SY100EPT28L转换器，电平移位器逻辑转换器或电平移位器 IC 可用于在数字逻辑设备之间传递信息，这些设备可在不同/不兼容的供电电压下工作，或可实现不同的信令方式。例如，可以将需要 5 V 电源的数字输出传感器连接到具有 3.3 V I/O 电源的 FPGA，或者在 CMOS 或 TTL 等单端信令方式与 PECL 或 LVDS 等差分技术之间进行转换。
