SY89328L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 SY89328L is a differential LVPECL-to-LVTTL translator and an LVTTL-to-differential LVPECL translator in a single package. Because LVPECL (Positive ECL) levels are used, only +3.3V and ground are required. The SY89328L is functionally equivalent to the SY100EPT28L, but in an ultra-small 8-lead MLF™ package that features a 70% smaller footprint. This ultra-small package and the dual translation design of the SY89328L make it ideal for applications that are sending and receiving signals across a backplane.

特性 Features

• 3.3V ±10% power supply
• Guaranteed AC parameters over temperature: fMAX > 275MHz (LVTTL)
• < 2ns LVPECL-to-LVTTL propagation delay
• < 600ps LVTTL-to-LVPECL propagation delay
• Internal 75kΩ input pull-up and pull-down resistors
• Industrial temperature range: -40°C to +85°C
• Available in ultra-small 8-pin MLF™ (2mm x 2mm) package

简介

SY89328L属于集成电路（IC）的转换器电平移位器。由制造生产的SY89328L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。
