MC74AC259, MC74ACT259 8-Bit Addressable Latch The MC74AC259/74ACT259 is a high−speed 8−bit addressable latch designed for general purpose storage applications in digital systems. It is a multifunctional device capable of storing single line data in eight addressable latches, and also a 1−of−8 decoder and demultiplexer with active HIGH outputs. The device also incorporates an active LOW Common Clear for resetting all latches, as well as an active LOW Enable. It is functionally identical to the ALS259 8−bit addressable latch. • • • • • • • MR E D Q7 Q6 Q5 Q4 16 15 14 13 12 11 10 9 MARKING DIAGRAM 16 Serial−to−Parallel Conversion Eight Bits of Storage with Output of Each Bit Available Random (Addressable) Data Entry Active High Demultiplexing or Decoding Capability Easily Expandable Common Clear These are Pb−Free Devices VCC www.onsemi.com SOIC−16 D SUFFIX CASE 751B 16 1 xxx259G AWLYWW 1 xxx A WL Y WW G = AC or ACT = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 8 of this data sheet. 1 2 3 4 5 6 7 8 A0 A1 A2 Q0 Q1 Q2 Q3 GND Figure 1.

FUNCTIONAL DESCRIPTION In the one−of−eight decoding or demultiplexing mode, the addressed output will follow the state of the D input with all other outputs in the LOW state. In the clear mode all outputs are LOW and unaffected by the address and data inputs. When operating the MC74AC/ACT259 as an addressable latch, changing more than one bit of the address could impose a transient wrong address. Therefore, this should only be done while in the memory mode. The Mode Select Function Table summarizes the operations of the MC74AC/ACT259. The MC74AC259/74ACT259 has four modes of operation as shown in the Mode Selection 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 state and are unaffected by the Data or Address inputs. www.onsemi.com 2 MC74AC259, MC74ACT259 Q7 Q6 Q5 MR Q4 Q3 A2 A1 Q2 A0 Q1 D E Q0 NOTE: This diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
