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.

簡介

SY89321L屬于集成電路（IC）的轉換器電平移位器。由制造生產的SY89321L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。
