SN74HC4852N
物料型号: - SN74HC4852

器件简介: - 该器件是一个双4通道模拟多路复用器/解复用器,与4052功能引脚兼容,并具有注入电流效应控制。这种特性在汽车应用中非常有价值,因为那里的电压可能会超过正常供电电压。 - 注入电流效应控制允许禁用的模拟输入通道的信号超过供电电压,而不影响启用的模拟通道的信号。这消除了通常需要外部二极管/电阻网络来保持模拟通道信号在供电电压范围内的需求。

引脚分配: - 引脚1: VCC - 引脚2: Y0 - 引脚3: Y1 - 引脚4: Y2 - 引脚5: Y3 - 引脚6: 2-COM - 引脚7: GND - 引脚8: 1-COM - 引脚9: 1Y3 - 引脚10: 1Y0 - 引脚11: 1Y1 - 引脚12: 1Y2 - 引脚13: A - 引脚14: B - 引脚15: INH - 引脚16: NC(无内部连接)

参数特性: - 供电电压范围:2V至6V - 输入电压范围:-0.5V至Vcc + 0.5V - 开关/输出电压范围:-0.5V至Vcc + 0.5V - 输入钳位电流:+20 mA - 输出二极管电流:20 mA - 开关通过电流:+25 mA - 通过Vcc或GND的连续电流:±50 mA - 封装热阻:D封装73°C/W,DGV封装120°C/W,N封装67°C/W,PW封装108°C/W - 存储温度范围:-65°C至150°C

功能详解: - 该器件具有注入电流效应控制,可以控制禁用模拟输入通道的信号,使其超过供电电压而不影响启用通道的信号。 - 功能表显示了输入信号和启用通道之间的关系。

应用信息: - 提供了应用电路图,展示了如何使用SN74HC4852来减少标准HC4052多路复用器的注入电流。 - 展示了双极性耦合机制的图解,如果VIn超过VCC,会驱动注入电流进入基底。

封装信息: - 提供了多种封装选项,包括PDIP、SOIC、TSSOP、TVSOP等。 - 每种封装的引脚数、封装类型、封装尺寸、热阻、工作温度范围和样品标记都有详细说明。
