Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

General Description
The 74AC541 and 74ACT541 are octal buffer/line
drivers designed to be employed as memory and
address drivers, clock drivers and bus oriented transmitter/
receivers.
These devices are similar in function to the 74AC244
and 74ACTC244 while providing flow-through architec-
ture (inputs on opposite side from outputs). This pinout
arrangement makes these devices especially useful as
an output port for microprocessors, allowing ease of
layout and greater PC board density.
easier interface to microprocessors

我最近在《华尔街日报》看到一篇题为“我们需要能维修自己的电子小玩意儿的权利(We need the right to repair our gadgets)”的文章(参考原文：)，作者对于众多电子产品看来是“有计画的废弃(planned obsolescence)”之现象非常愤怒，认为大众应该要求电子产品可以被维修。 但实际的情况是，举例来说，家家都有的电视机如果故障了，修理费用可能...[详细]
