SN74LV573ATDGVRG4 - Texas Instruments Octal Transparent D-Type Latches

The SN74LV573ATDGVRG4 is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments. This integrated circuit is part of the 74LV family, which is known for its low-voltage operation and compatibility with TTL-level logic. The device is ideal for applications that require the temporary storage of data and possess the capability to hold this data available at the outputs until it is required.

Operating within a voltage range of 2V to 5.5V, the SN74LV573ATDGVRG4 provides a flexible solution for interfacing with both 3.3V and 5V systems. This makes it particularly suitable for mixed-voltage environments, ensuring seamless integration into a wide variety of digital systems. The low-voltage operation also contributes to the reduction of power consumption, making it a power-efficient choice for modern electronic designs.

The device features eight D-type latches with 3-state 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. Moreover, the output-enable (OE) feature allows the user to place the eight outputs in either a normal logic state or a high-impedance state. This high-impedance state is crucial when multiple devices are connected to a common bus, as it prevents bus contention.

The SN74LV573ATDGVRG4 is offered in a thin shrink small-outline package (TSSOP), designated by the DGVR suffix, which is ideal for space-constrained applications. The G4 at the end of the part number signifies that it is a lead-free (RoHS compliant) and green (halogen-free) component, reflecting Texas Instruments' commitment to environmental sustainability.

With its robust latch function, low-power consumption, and compact form factor, the SN74LV573ATDGVRG4 is a versatile component suitable for a wide range of applications, including computers, servers, networking, telecommunications, and industrial control systems where reliable data storage and retrieval are essential.
