Overview
The MC74ACT540DTR2G is an octal buffer/line driver with 3-state outputs, produced by onsemi. This device is part of the 74ACT series, which is known for its high-speed and low-power CMOS logic. It is designed to be used as memory and address drivers, clock drivers, and bus-oriented transmitter/receivers. The MC74ACT540 provides inverted outputs, while its noninverting counterpart is the MC74ACT541.
