Functional Features
The 74ALVC373PW,112 is an octal transparent latch with 3-state outputs. It allows for the storage of data on its inputs and provides the ability to enable or disable the outputs. The latch is transparent when the latch enable (LE) input is high, allowing the data inputs to pass through to the outputs. When the LE input is low, the latch holds the last data present at the inputs.
The output enable (OE) input controls the 3-state outputs. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus lines. When OE is low, the outputs reflect the data stored in the latch.
Advantages and Disadvantages
Advantages
- Low power consumption makes it suitable for battery-powered devices.
- Wide operating voltage range allows compatibility with various systems.
- Schmitt-trigger inputs provide noise immunity, ensuring reliable operation.
