概览

高性能硅门极 CMOS MC74HCT573A 与 LS573 的引脚输出相同。此器件可用作将 TTL 或 NMOS 输出联接到高速 CMOS 输入的电平转换器。此类锁存在锁存启用为高电平时对于数据透明（即输出异步变化）。当锁存启用进入低电平时，符合设置和保持时间要求的数据变为锁存状态。输出启用输入不影响锁存的状态，但当输出启用为高电平时，所有器件输出都被强制为高阻抗状态。因此，即使在输出不启用时也可锁存数据。HCT573A 与 HCT373A 功能相同，但在封装的输出对侧上具有数据输入，简化了 PC 主板布局。

  • Output Drive Capability: 15 LSTTL Loads
  • TTL/NMOS-Compatible Input Levels
  • Outputs Directly Interface to CMOS, NMOS and TTL
  • Operating Voltage Range: 4.5 to 5.5 V
  • Low Input Current: 10 mA
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 234 FETs or 58.5 Equivalent Gates
    - Improved Propagation Delays
    - 50% Lower Quiescent Power
  • 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.

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.)
