SN74LV573ADWR

The SN74LV573ADWR is a high-speed, low-voltage octal D-type latch designed by Texas Instruments. It is part of the 74LV family of logic devices, which are known for their low power consumption and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

• Type: Octal D-type latch
• Functionality: The device consists of eight latches that can store data on the rising edge of the clock signal. It is designed to hold data when the enable signal is low and to allow data to pass through when the enable signal is high.

Key Features:

• Supply Voltage: Operates with a supply voltage range of 2.0V to 5.5V, making it suitable for low-voltage applications.
• Data Input: Each of the eight latches has a corresponding data input (D0 to D7) that accepts standard logic levels.
• Output: The outputs (Q0 to Q7) are capable of driving standard TTL loads, providing a high degree of compatibility with other logic families.
• Clock Input: The device features a clock input (CLK) that triggers the latching of data on the rising edge.
• Enable Input: An active-low enable input (G) allows the user to control when the latches are transparent (data can pass through) or latched (data is held).
• Propagation Delay: The device boasts a fast propagation delay, typically around 5 ns at 5V, allowing for high-speed operation in digital circuits.
• Power Consumption: The SN74LV573ADWR is designed for low power consumption, making it ideal for battery-operated devices and energy-efficient applications.

Package Information:

• Package Type: The device is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for surface-mount technology (SMT).
• Dimensions: The TSSOP package typically measures approximately 4.4 mm x 6.5 mm, with a height of about 1 mm, allowing for space-saving designs on PCBs.

Electrical Characteristics:

• Input Voltage Levels: The input high voltage (VIH) is typically 2.0V (at VCC = 3.3V) and 3.5V (at VCC = 5V), while the input low voltage (VIL) is typically 0.8V.
• Output Voltage Levels: The output high voltage (VOH) is typically close to VCC, while the output low voltage (VOL) is typically near ground.
• Current Ratings: The device can source or sink a maximum of 35 mA per output, making it versatile for various applications.

Applications:

The SN74LV573ADWR is commonly used in applications such as:

• Data storage and transfer in digital circuits
• Temporary data holding in microcontroller interfacing
• Buffering data in communication systems
• Implementing state machines and control logic in various electronic devices

Conclusion:

The SN74LV573ADWR from Texas Instruments is a versatile and efficient octal D-type latch that combines high-speed performance with low power consumption, making it an excellent choice for modern digital applications. Its compact package and robust electrical characteristics make it suitable for a wide range of electronic designs.
