74LV259 8-bit Adressable Latch

The 74LV259 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC259 and 74HCT259. The 74LV259 is a high-speed 8-bit addressable latch designed for general purpose storage applications in digital systems. The 74LV259 is multifunctional 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. The 74LV259 also incorporates 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. In the 3-to-8 decoding or demultiplexing mode, the addressed output follows the state of the (D) input with all other outputs in the LOW state. In the reset mode all outputs are LOW and unaffected by the address (A0 to A2) and data (D) input. When operating the 74LV259 as an address latch, changing more than one bit of address could impose a transient-wrong address. Therefore, this should only be done while in the memory mode.
