Additional Details

The TC74ACT573FT(EL) features eight D-type latches, each capable of storing one bit of data. The latches are enabled by a common latch enable (LE) input. When LE is high, the outputs follow the data inputs. When LE is low, the outputs latch the data present at the inputs. The 3-state outputs allow the device to be connected to a common data bus without loading the bus when the outputs are disabled. The high-speed operation of the ACT family ensures fast data transfer and processing. The low power consumption makes it suitable for battery-powered applications. The device operates over a wide voltage range, typically 4.5V to 5.5V. Detailed timing characteristics and electrical specifications are available in the product datasheet. This octal latch is a fundamental building block in many digital systems, providing temporary data storage and buffering capabilities.
