XBLW SN74HC259N(XBLW)

The SN74HC259 is an 8-bit addressable latch. This device offers four operating modes. In addressable latch mode, data at the D input is written into the latch addressed by inputs A0 through A3. The addressed latch follows the data input, while unaddressed latches retain their previous states. In memory mode, all latches retain their previous states regardless of data or address inputs. In 3-line-to-8-line decode or demultiplex mode, the addressed output follows the D input while all other outputs are held low. In reset mode, all outputs are forced low regardless of data or address inputs. The inputs include clamping diodes, which allow the use of current-limiting resistors to interface inputs to voltages exceeding VCC.
