概览

VHC123A 是一种先进的高速 CMOS Monostable 多谐振荡器，采用硅门极 CMOS 工艺制造。它能实现与同等双极肖特基 TTL 相似的高速运行，同时还能保持 CMOS 低功耗。每个多谐振荡器均具有一个负极 A 和一个正极 B 转换触发输入，均可用作抑制输入。还包括了一个清除输入，如果以低电平采用则会重置一次性操作。VHC123A 可在该清除输入进行正极转换时触发，同时 A 保持在低电平，B 保持在高电平。输出脉冲宽度有该公式确定： PW = (Rx)(Cx)；其中 PW 为秒数，R 为欧姆数，C 为华氏度。Rx 和 Cx 限值为： 外部电容器，CxNo 限值外部电阻，Rx VCC = 2.0V，5 kohm 最小 VCC > 3.0V，1 kohm 最小 An 输入保护电路确保可对输入引脚应用 0 到 7V 电压，而不用考虑电源电压。此器件可用于将 5V 系统与 3V 系统以及两种电源系统的接口，如备用电池。此电路可防止器件由于不匹配的供电和输入电压而损坏。

  • This product is general usage and suitable for many different applications.
  • 高速： TA = 25°C时，tPD = 8.1 ns（典型值）
  • 低功耗：TA = 25°C时，ICC = 4 µA（最大值）
  • 有效状态： ICC = 600 µA（最大值），TA = 25°C时
  • 高抗噪能力： VNIH = VNIL = 28% VCC （最小值）
  • 所有输入上都提供掉电保护
  • 引脚和功能与74HC123A兼容
