74HC573PW,118

The 74HC573PW,118 is a high-speed CMOS octal transparent latch from Nexperia, designed for use in digital circuits. This device is part of the 74HC family, which is known for its high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:

General Description:

• Type: Octal Transparent Latch
• Package: TSSOP (Thin Shrink Small Outline Package)
• Pin Count: 20 pins
• Functionality: The 74HC573 is designed to store 8 bits of data. It operates as a transparent latch, meaning that when the latch enable (LE) input is high, the output follows the input. When LE is low, the output holds the last value present at the input.

Key Features:

• High-Speed Operation: The device can operate at high frequencies, making it suitable for fast digital applications.
• Low Power Consumption: The CMOS technology used in the 74HC573 ensures low static and dynamic power consumption.
• Wide Supply Voltage Range: It typically operates with a supply voltage range of 2V to 6V, making it versatile for various applications.
• Input and Output Compatibility: The device is compatible with standard TTL levels, allowing it to interface with other logic families.
• Tri-State Outputs: The outputs can be placed in a high-impedance state, allowing multiple devices to share the same output line without interference.

Electrical Characteristics:

• Supply Voltage (Vcc): 2V to 6V
• Input Voltage (Vi): 0V to Vcc
• Output Voltage (Vo): 0V to Vcc
• Maximum Input Current (Ii): ±20 µA
• Maximum Output Current (Io): ±25 mA
• Propagation Delay: Typically around 15 ns at Vcc = 5V
• Power Dissipation: Low, typically around 1 µA in static conditions.

Pin Configuration:

The 74HC573PW,118 has a specific pin configuration that includes:

• Data Inputs (D0-D7): Eight data input pins for the latch.
• Latch Enable (LE): A control pin that determines when the latch is transparent.
• Output Enable (OE): A control pin that enables or disables the output.
• Outputs (Q0-Q7): Eight output pins that reflect the state of the inputs when the latch is enabled.
• Ground (GND): The ground connection for the device.
• Vcc: The power supply connection.

Applications:

The 74HC573 is commonly used in various applications, including:

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

Conclusion:

The 74HC573PW,118 from Nexperia is a versatile and efficient octal transparent latch suitable for a wide range of digital applications. Its combination of high-speed performance, low power consumption, and compatibility with other logic families makes it an excellent choice for modern electronic designs.
