概览

MC74VHCT50A 是一款六路非反向缓冲器，使用硅门极 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。内部电路由三级组成，包括一个提供高抗扰性和稳定输出的缓冲器输出。该器件输入可兼容 TTL 型输入阈值，输出则具有全 CMOS 电平输出摆幅。此器件上的输入保护电路允许输入上的耐过电压，使得此器件能够用作从 3.0 V CMOS 逻辑进行转换的逻辑电平转换器，且能在高电压电源下运行。MC74VHCT50A 输入结构在应用高达 7.0 V 的电压时提供保护，而无论电源电压如何。因此使得 MC74VHCT50A 可用作 5 V 到 3 V 电路的接口。输出结构还会在 VCC = 0V 时提供保护。这些输入和输出结构有助于防止电源电压 - 输入/输出电压不匹配、电池备用、热插入等导致的器件损坏。

  • High Speed: tPD = 3.5ns (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 2mA (Max) at TA = 25°C
  • TTL-Compatible Inputs: VIL = 0.8V; VIH = 2.0V
  • CMOS-Compatible Outputs: VOH > 0.8VCC; VOL < 0.1VCC @Load
  • Power Down Protection Provided on Inputs and Outputs
  • These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
