The SN74LV573ATDBRE4 is a versatile logic latch with enhanced speed, waveform characteristics, input thresholds and noise immunity. It belongs to the logic latch family, used for data latching applications. In logic latch, either input or output can change independently at any time and the data is stored in the output. The integrated latch is designed to be used in memory systems and other applications requiring guaranteed data integrity.

The SN74LV573ATDBRE4 is a 32-bit latch, similar to that of a 4x8 multiplexed latch architecture, integrated within a 64-pin QFP package with two power supply pins. It is a low-voltage device and includes logic gates to support data outputs up to 5.5V for a minimum of 3V. The logic latch exhibits maximum speed performance with a propagation delay time at a maximum of 7.3ns and an output skew of less than 1.1ns. Low power consumption is enabled with a dynamic power consumption of 5mW.

In terms of its input characteristics, the SN74LV573ATDBRE4 has 8 differential active high inputs. These inputs are TTL compatible and optimized for clock signal applications. The device is provided with two power supplies pins, wherein one is a control signal VDDO and the other is a logic signal VDDI. VDDO voltage is used to determine the output voltage, while VDDI is used to indicate the device logic. It can operate at 3.3V, 5V or 5.5V.

The SN74LV573ATDBRE4 is composed of two series-connected latches, to form a double latch system. This allows each flip-flop to operate independently. The enD latch enables the latch to be turned on and off for each data bit separately. If the enD signal is low, the enabled flip-flop is recorded, and if the enD signal is high, the flip-flop is turned off.

In terms of its application field, the SN74LV573ATDBRE4 can be used in a variety of memory system architecture such as disks and SSDs as a primary or secondary latch. Additionally, the device is also suitable for applications in consumer electronics or gaming consoles and audio/visual devices, which require reliable data storage. Moreover, the device can be used in interface and storage devices such as, digital-to-analog converters, ADC, flash, EPROM and DRAM.

The SN74LV573ATDBRE4 is powered by an integrated energy-saving low-voltage design and can handle clock applications of up to 5.5V. Its minimal capacitance and low voltage levels results in low power consumption, fewer cross-talk and noise, and high speed. Its features and design allows for a wide range of applications, including interfaces, memory systems, latching and data acquisition.
