Description

The 74LV573DB is a high-speed, low-voltage CMOS octal D-type latch with a tri-state output. It is part of the 74LV family, designed to operate with a supply voltage range of 2.0V to 5.5V, making it suitable for battery-operated devices and low-power applications.
This device features eight data inputs (D0-D7), an output enable (OE) pin, and a latch enable (LE) pin. When the LE pin is activated, the data present at the inputs is captured and held. The outputs can be controlled via the OE pin, allowing for tri-state functionality, which means the outputs can be set to high impedance.
The 74LV573DB is commonly used in digital circuits for temporary data storage, buffering, and interfacing applications. It provides high-speed operation and is compatible with TTL levels, making it versatile for various electronic projects and systems. The device is housed in a 20-pin SOIC package, suitable for surface mount technology.

Features

The 74LV573DB is a low-voltage, high-speed octal D-type latch with 3-state outputs. Key features include:
1. Data Latching: It has 8 latches controlled by a common clock, allowing simultaneous data storage.
2. 3-State Outputs: The outputs can be in a high (active), low (active), or high-impedance state, facilitating bus-oriented communication.
3. Voltage Range: Operates with a supply voltage of 2.0V to 5.5V, making it suitable for low-voltage applications.
4. Fast Switching: TTL-compatible with a propagation delay of around 5 ns at 5V.
5. Input Compatibility: Accepts standard TTL input levels.
6. Package: Available in a 20-pin DIP or SOIC package, suitable for surface mount applications.
7. Reset Function: Includes an asynchronous reset feature to clear latches.
This device is widely used in digital circuits for data buffering, temporary storage, and synchronization tasks.

Package

The 74LV573DB package type is a 20-pin Dual In-Line Package (DIP). It features a plastic body and is designed for through-hole mounting.

Pinout

The 74LV573DB is an octal transparent latch with 3-state outputs. It features 20 pins in total. The pin configuration is as follows:
1. Data Inputs (D0-D7): Pins 1-8 for data input.
2. Output Enable (OE): Pin 9 controls the output enable function. When low, outputs are enabled; when high, outputs are in a high-impedance state.
3. Latch Enable (LE): Pin 10 controls the latching function. When low, data is transparent (input follows output); when high, data is latched on the rising edge of LE.
4. Data Outputs (Q0-Q7): Pins 11-18 for the latched output corresponding to the data inputs.
5. GND: Pin 19 connects to ground.
6. VCC: Pin 20 connects to the positive power supply.
This device is commonly used in applications requiring data storage and transfer, providing flexibility in digital circuits.
