Philips 74LV259
The 74LV259 is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT259. The 74LV259 is a high-speed 8-bit addressable latch designed for general purpose storage applications in digital systems. The 74LV259 is a multifunction device capable of storing single-line data in eight addressable latches, and also 3-to-8 decoder and demultiplexer, with active HIGH outputs (Q0 to Q7), functions are available.| Part No. | 74LV259 |

DESCRIPTION
The 74LV259 also incorporate an active LOW common reset (MR) for resetting all latches, as well as an active LOW enable input (LE). The 74LV259 has four modes of operation as shown in the mode select table. In the addressable latch mode, data on the data line (D) is written into the addressed latch. The addressed latch will follow the data input with all non-addressed latches remaining in their previous states. In the memory mode, all latches remain in their previous states and are unaffected by the data or address inputs.
