SN74LV573ATRGYRG4 Octal Transparent D-Type Latches by Texas Instruments

The SN74LV573ATRGYRG4 is a high-performance, octal transparent D-type latch designed by Texas Instruments. This integrated circuit is part of the SN74 family, which is renowned for its reliability and versatility in a wide range of digital applications. With its advanced low-voltage CMOS technology, it offers optimal power and speed characteristics, making it suitable for interfacing with 5-V TTL logic while operating at a voltage range of 2 V to 5.5 V.

Featuring a latch-up performance that exceeds 250 mA per JESD 17, the SN74LV573ATRGYRG4 is equipped with eight latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. However, when LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. This transparent mode of operation allows for real-time data flow when latching is not needed. The 3-state outputs, which are controlled by the output-enable (OE) input, can be placed in either a high-impedance OFF-state or active low state, providing a convenient way to interface with buses or other peripheral components.

Encased in a thin shrink small-outline package (TSSOP), the SN74LV573ATRGYRG4 is designed for space-constrained applications, while still delivering the robustness expected from Texas Instruments' products. It is also characterized for operation from -40°C to 85°C, ensuring reliable performance across a broad range of environmental conditions.

Applications for this latch include data storage, data gating, and buffer storage in computers, communication systems, and other digital systems where high-speed, low-power latch functions are required. Its ease of use and high functionality make the SN74LV573ATRGYRG4 a preferred choice for designers who seek to create efficient and reliable digital logic systems.
