DESCRIPTION
The M74HCT7259 is an high speed CMOS 8 BIT
ADDRESSABLE LATCH/DECODER fabricated
with silicon gate C2MOS technology.
This device has single data input (D) 8 LATCH
inverted OUTPUTS (Q0 - Q7), 3 address inputs
(A, B and C), common enable input (ENABLE)
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 address output. The data is stored
on the positive going edge of the ENABLE pulse.
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 the HIGH (OFF) state. If ENABLE is low
all latches except the addressed latch will be
cleared. The address latch will instead be the
complement
of
the
D
input,
effectively
implementing a 3 to 8 line decoder. Internal clamp
diodes protect the open drain outputs against over
voltages due to inductive loads.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
