Présentation
Description
This device features eight latches controlled by a single clock input. When the clock is enabled, data on the input pins is latched and held until the clock is triggered again. The three-state outputs allow it to drive multiple devices on a bus, enabling efficient data communication between components.
The 74HCT573D operates within a voltage range of 4.5V to 5.5V, making it suitable for a wide range of electronic systems. Its low power consumption and reliable performance make it a popular choice in applications such as microcontrollers, data acquisition systems, and communication interfaces. The device is typically available in a 20-pin DIP or surface-mount package.

Pinout
Here are the key pin functions:
- Pins 1-8 (Q0-Q7): Outputs of the flip-flops.
- Pins 9-16 (D0-D7): Data inputs for the flip-flops.
- Pin 10 (GND): Ground connection.
- Pin 11 (OE): Output enable. When low, the outputs are enabled; when high, they are in a high-impedance state.
- Pin 12 (CLK): Clock input. Data at the D inputs is captured on the rising edge of this clock signal.
- Pin 13 (LE): Latch enable. When high, the data is latched into the flip-flops; when low, the outputs follow the inputs.
- Pin 14 (VCC): Supply voltage (typically +5V).
The 74HCT573D is commonly used in digital circuits for temporary storage of data and for implementing registers.
