8-bit Addressable Latch

Description

The HD74HC259 has a single data input (D), 8 latch outputs (Q₀-Q₇), 3 address inputs (A, B, and C), a common enable

input (E), and a common 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. The data is stored when enable transitions from low to high. All

unaddressed latches will remain unaffected. With enable in the high state the device is deselected, and all latches

remain in their previous state, unaffected by changes on the data or address inputs. To eliminate the possibility of

entering erroneous data into the latches, the enable should be held high (inactive) while the address lines are changing.

If enable is held high and clear is taken low all eight latches are cleared to a low state. If enable is low all latches except

the addressed latch will be cleared. The addressed latch will instead follow the D input, effectively implementing a 3-

to-8 line decoder.
