Working Principles

The 74LV259BQ,115 is an addressable latch with 3-state outputs. It consists of eight input pins (A0-A7) used to select the desired data input, and three output pins (Q0-Q2) that provide the selected data. The latch is controlled by the latch enable (LE) pin, which captures the input data when activated. The output enable (OE) pin controls the output state, allowing the outputs to be either active or in a high-impedance state.

Detailed Application Field Plans

The 74LV259BQ,115 can be used in various electronic applications, including but not limited to: - Data multiplexing in microcontrollers and digital systems. - Address decoding in memory systems. - Input/output expansion in embedded systems. - Signal routing and selection in audio/video equipment.
