DM74AS373  
Octal D-Type Transparent Latch with 3-STATE Outputs  
General Description  
Features  
These 8-bit registers feature totem-pole 3-STATE outputs  
designed specifically for driving highly-capacitive or rela-  
tively low-impedance loads. The high-impedance state and  
increased high-logic-level drive provide these registers with  
the capability of being connected directly to and driving the  
bus lines in a bus-organized system without need for inter-  
face or pull-up components. They are particularly attractive  
for implementing buffer registers, I/O ports, bidirectional  
bus drivers, and working registers.  
Switching specifications at 50 pF  
Switching specifications guaranteed over full tempera-  
ture and VCC range  
Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
Functionally and pin for pin compatible with LS and ALS  
TTL counterparts  
Improved AC performance over LS and ALS TTL coun-  
terparts  
The eight latches of the DM74AS373 are transparent D-  
type latches, meaning that while the enable (G) is HIGH  
the Q outputs will follow the data (D) inputs. When the  
enable is taken LOW the output will be latched at the level  
of the data that was set up.  
3-STATE buffer-type outputs drive bus lines directly  
A buffered output control input can be used to place the  
eight outputs in either a normal logic state (HIGH or LOW  
logic levels) or a high impedance state. In the high-imped-  
ance state the outputs neither load nor drive the bus lines  
significantly.  
The output control does not affect the internal operation of  
the latches. That is, the old data can be retained or new  
data can be entered even while the outputs are OFF.
