产品

概览

为汽车应用定制。此器件可与标准 HC4051 和 MC14051B 模拟多路复用器/信号分离器实现引脚兼容，但具有注入电流效应控制。因此，此类器件尤其适用于汽车应用，其中超过正常逻辑电压的电源非常普遍。注入电流效应控制允许已禁用模拟输入沟道处的信号超过电源电压范围，而不会影响已启用模拟沟道的信号。因此无需外部二极管/电阻网络即可将模拟沟道信号保持在电源电压范围内。此类器件使用低功耗硅门极 CMOS 工艺。沟道选择和启用输入与标准 CMOS 或 LSTTL 输出兼容。

  • White Goods, Desktop, Industrial, etc;

  • Injection Current CrossCoupling Less than 1mV/mA
  • Pin Compatible to HC4051 and MC14051B Devices
  • Power Supply Range (VCC GND) = 4.5 to 5.5 V
  • In Compliance With the Requirements of JEDEC Standard No. 7A
  • Chip Complexity: 154 FETs or 36 Equivalent Gates
  • These are PbFree Devices

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
