74HC(T)423：双可再触发单稳态多谐振荡器，带重置

74HC423；74HCT423是高速硅栅CMOS器件，与低功耗肖特基TTL (LSTTL)针脚兼容。其规格符合JEDEC标准no. 7A。

带复位的74HC423；74HCT423双可再触发单稳态多谐振荡器具有两种输出脉冲宽度控制方法。

nA和nB输入的施密特触发器动作使其高度容许较慢的输入上升和下降时间。

74HC423；74HCT423等同于74HC123；74HCT123，但无法通过复位输入触发。

特性和优势
    • 从高电平有效或低电平有效输入触发的直流
    • 针对占空系数高达100 %的极长脉冲可再触发
    • 直接复位可终止输出脉冲
    • 除复位输入外的所有输入上的施密特触发器动作
    • 符合JEDEC标准no. 7A
    • ESD保护：
      • HBM JESD22-A114F超过2000 V
      • MM JESD22-A115-A超过200 V
    • HBM JESD22-A114F超过2000 V
    • MM JESD22-A115-A超过200 V
    • 额定温度范围为-40 °C至+85 °C和-40 °C至+125 °C
