SY89321L中文资料Translators数据手册Microchip规格书

描述 Description

The SY89321L is a differential LVPECL/CML/LVDSto-LVTTL translator requiring only a single +3.3V power.The SY89321L is functionally equivalent to the SY100EPT21L, but in an ultra-small 8-pin MLF® package that features a 70% smaller footprint. This ultra-small package and low skew single gate design make the SY89321L ideal for applications that require the translation of a clock or data signal where minimal space, low power and low cost are critical.VBB allows a differential, single-ended, or AC-coupled interface to the device. If used, the VBB output should be bypassed to VCC with 0.01µF capacitor.Under open input conditions, the /IN will be biased at a VCC/2 voltage level and the IN input will be pulled to ground. This condition will force the Q output low to provide added stability.The SY89321L is compatible with positive ECL 100k logic levels.

简介

SY89321L属于集成电路（IC）的转换器电平移位器。由制造生产的SY89321L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。
