产品描述:
SN74LVCC4245A是一款8位(八进制)同相总线收发器,使用两个独立的电源轨。A端口(VCCA)专用于接受5 V电源电平,而可配置B端口用于跟踪VCCB,可接受3 V至5 V的电压。这允许从3.3 V环境转换到5 V环境,反之亦然。
SN74LVCC4245A专为数据总线之间的异步通信而设计。根据方向控制(DIR)输入端的逻辑电平,该器件将数据从A总线传输到B总线,或从B总线传输到A总线。可使用输出使能(OE)输入禁用设备,从而有效隔离总线。控制电路(DIR,OE)由VCCA供电。产品特性:

(1) Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.
