The M74HCT7259 is a high speed CMOS 8 BIT  
ADDRESSABLE LATCH/DECODER fabricated in  
silicon gate C2MOS technology. It has the same  
high speed performance of LSTTL combined with  
true CMOS low power consumption.  
The M74HCT7259 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 addressablelatch, 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 unadressed 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  
DIP

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  
inductiveloads.  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.
