Functional Features
- Octal D-type transparent latch with 3-state outputs.
- Latch enable (LE) and output enable (OE) control inputs.
- When LE is high, the latch is transparent, allowing data to flow from the inputs to the outputs.
- When OE is low, the outputs are in a high-impedance state.
- Suitable for level shifting applications where different voltage levels need to be interfaced.
Advantages and Disadvantages
Advantages: - Wide supply voltage range allows compatibility with various systems. - High-speed operation with low propagation delay time. - 3-state outputs provide flexibility in bus-oriented applications.
Disadvantages: - Limited output current capability may restrict usage in certain high-current applications. - TSSOP package may require careful handling during assembly.
Working Principles
The 74LV573PW,118 operates as an octal D-type transparent latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The output enable (OE) input controls whether the outputs are active or in a high-impedance state. This IC is designed to shift logic levels, allowing interfacing between different voltage domains.
Detailed Application Field Plans
The 74LV573PW,118 can be used in various applications, including but not limited to: - Microcontroller interfacing - Data bus buffering - Level shifting in mixed-voltage systems - Address decoding in memory systems - General-purpose digital logic applications
