The MM74HC259M is an 8-bit addressable latch designed for general-purpose storage applications in digital systems. It features a single data input (D), eight latch outputs (Q1,ÄìQ8), three address inputs (A, B, and C), a common enable input (G), and a common clear input. The device operates by holding data on the D input while the address is specified on the A, B, and C inputs. When the enable input is taken LOW, the data is transferred to the addressed output, and the data is stored when the enable transitions from LOW to HIGH. The MM74HC259M supports a supply voltage range of 2 to 6V and has a typical propagation delay of 18 ns. It is characterized by low input and quiescent current, with a maximum input current of 1 mA and a maximum quiescent current of 80 mA. The device is available in multiple package types, including a 16-lead Small Outline Integrated Circuit (SOIC) and a 16-lead Plastic Dual-In-Line Package (PDIP). All inputs are protected against static discharge, enhancing reliability in various applications.
