Working Principles

The 74LCX573FT(AE) is an octal transparent latch that stores and outputs 8 bits of data. The latch is controlled by the latch enable (LE) signal, which determines when the input data is stored. The output enable (OE) signal controls whether the stored data is presented at the outputs or not.

When the LE signal is high, the latch is transparent, allowing the input data to pass through and be stored. When the LE signal is low, the latch holds the stored data. The OE signal, when high, enables the outputs, allowing the stored data to be presented. When the OE signal is low, the outputs are in a high-impedance state.

Detailed Application Field Plans

The 74LCX573FT(AE) can be used in various applications, including but not limited to:

1. Data storage and retrieval systems
