The SN74ABT573ADWRG4 provides eight D-type latches with three-state standard outputs. 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 latter mode, the outputs neither load nor drive the bus lines significantly, thus effectively isolating the bus.

The device's use of 20-pin SOIC (Small Outline Integrated Circuit) packaging allows for a compact footprint, while still providing robustness for through-hole or surface-mount assembly processes. The SN74ABT573ADWRG4 is characterized for operation from -40°C to +85°C, ensuring reliability across a wide range of environmental conditions.

With its fast propagation delay and edge-rate control circuitry, the SN74ABT573ADWRG4 minimizes the effects of output transitions and simplifies the design of high-speed memory addressing and data bus systems. Whether you are designing a high-speed microprocessor interface or a state-of-the-art communication system, the SN74ABT573ADWRG4 from Texas Instruments offers the performance and features necessary for a successful implementation.
