Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FSA2457 — 四路单刀双掷5Ω 模拟数据开关
特性
描述
FSA2457是双向的低功耗四路单刀双掷模拟开关专门针
对双路的1个字节的SIM/SD/MMC 卡和或GPS信号多路复
用器而设计。它对于切换WLAN-SIM数据和 52Mbps的控
制信号是最佳选择。
对于数据路径具有12pF的典型的低导通电容
对于数据路径具有5Ω的典型的低导通电阻
低功耗：1μA最大值
宽广的 -3db带宽: > 160MHz
FSA2457与1个字节的SIM/SD/MMC卡的要求相兼容并且
是连接GPS基带处理器的理想选择。双FSA2457拥有
12pF的低导通电容来确保高速数据的传送。
封装保证环境绿化16引脚的UMLP (1.8 x 2.6mm)
4kV JEDEC: JESD22-A114 HBM
2kV JEDEC: JESD22-C101 CDM
当供给 SEL 管脚的控制电压低于供电电压 时FSA2457因
包含有特殊的电路可以最小化电流的功耗, 这种特性在象
手机类超便携式应用中特别有价值, 通过它可以直接与基
带处理器通用I/O口连接. 其它应用包括在便携式手机,
PDAs, 数字相机, 打印机, 和便携式GPS系统的切换和连
接。
应用
手机, PDA, 数字相机, 便携式GPS
LCD显示屏, TV, 机顶盒

最大绝对额定值
超出绝对最大额定值会破坏设备 ,设备会不工作或者说不建议设备在和超过建议的工作条件下被操作。另外,过长的暴露
在超过建议工作条件下会影响设备的可靠性，这种绝对最大额定值仅仅是极端额定值。
