Performance and Applications

The SN74AHCT573N is characterized for operation from -40°C to 85°C, ensuring reliability over a wide range of environmental conditions. It provides the function of eight D-type latches in a single package, and when the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pull-up components.

This device is widely used in a variety of applications, including data storage, data buffering, and the capture of data at a specific moment in time. Its robust design and industry-standard package make it well-suited for use in complex electronic systems, such as computers, communication devices, and industrial control equipment.
