概览

高性能硅门极 CMOS MC74HCT373A 可用作电平转换器，从而将 TTL 或 NMOS 输出连接至高速 CMOS 输入。 HCT373A 与 LS373 的引脚输出相同。 HCT373A 的八个锁存为透明 D 型锁存。当锁存启用输入为高电平时，Q 输出将跟随数据输入。当锁存启用为低电平时，符合设置和保持时间要求的数据变为锁存状态。 输出启用不影响锁存的状态，但当输出启用为高电平时，所有输出均强制为高阻抗状态。因此，即使输出不启用数据也可锁存。 HCT373A 与 HCT573A 功能相同，后者在封装的输出引脚对侧上具有输入引脚。此器件的功能与 HCT533A 相似，后者具有反相输出。

  • 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: 1.0 mA
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 196 FETs or 49 Equivalent Gates
  • 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.)
