Overview
The MC74ACT573DTR2G, produced by onsemi, is a high-speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. This device is part of the 74ACT series, known for its TTL-compatible inputs and high-speed operation. It is functionally identical to the MC74ACT373 but has inputs and outputs on opposite sides of the package, facilitating easy interface with microprocessors.
