Description

The 74LVC573APW is an octal transparent latch designed for high-speed digital applications. It features a low-voltage CMOS technology, making it suitable for use in 3.3V systems while maintaining compatibility with 5V logic levels. The device consists of eight latches with a common data input (D) and a common output (Q) that can be controlled independently.
When the latch enable (LE) input is high, data present at the inputs is transferred to the outputs. When LE goes low, the outputs retain the last state, effectively "latching" the data. The 74LVC573APW also includes an active-low output enable (OE) pin for tri-state operation, allowing for easy interfacing with other digital circuits.
It is commonly used in applications where temporary data storage is needed, such as in bus systems, FIFO buffers, and general-purpose data manipulation tasks. The device's low power consumption and fast switching times make it ideal for modern electronic systems. It is available in a TSSOP package, which allows for compact PCB designs.

Features

The 74LVC573APW is an octal transparent latch designed for low-voltage CMOS applications. Key features include:
1. Octal Latch: Contains eight latches that store data.
2. Transparent Mode: Data is transferred to the outputs when the enable (E) input is high.
3. Low-Voltage Operation: Operates from 1.65V to 5.5V, making it suitable for battery-powered devices.
4. High-Speed Performance: Capable of fast switching times, enhancing system speed.
5. 3-State Outputs: Outputs can be placed in a high-impedance state, allowing for bus-oriented applications.
6. Power Consumption: Low static and dynamic power consumption, promoting energy efficiency.
7. Compatible with TTL: Accepts TTL input levels, ensuring compatibility with various logic families.
8. Pin Configuration: Available in a 20-pin TSSOP package, facilitating easy integration into designs.
Overall, the 74LVC573APW is ideal for applications requiring data storage with low power and high-speed performance.

Package

The 74LVC573APW is packaged in a TSSOP-20 (Thin Shrink Small Outline Package) format. This package type is designed for surface mounting and features a low profile, making it suitable for applications with space constraints on PCBs.

Pinout

The 74LVC573APW is an octal D-type flip-flop with a 3-state output, housed in a TSSOP-20 package. It has a total of 20 pins.
### Pin Count and Functions:
1. Pins 1-8: Data inputs (D0-D7)
2. Pin 9: Output enable (OE)
3. Pin 10: Clock input (CLK)
4. Pin 11: Latch enable (LE)
5. Pins 12-19: Data outputs (Q0-Q7)
6. Pin 20: Ground (GND)
### Key Functions:
- D0-D7: Accepts data inputs.
- CLK: Triggers the storage of data into flip-flops.
- LE: Controls whether data is latched (when high, data is stored on the next clock edge).
- OE: Controls the output state (active low).
- Q0-Q7: Provides the stored output data.
This device is typically used in applications requiring temporary data storage and manipulation in digital circuits.
