The HD74HC259 has a single data input (D), 8 latch outputs (Q0-Q7), 3 address inputs (A, B, and C), a mon enable input (E), and a mon clear input. To operate this device as an addressable latch, data is held on the D input, and the address of the latch into which the data is to be entered is held on the A, B and C inputs. When enable is taken low the data flows through to the addressed output.
