3-STATE Octal D-Type Transparent Latches  
and Edge-Triggered Flip-Flops  
General Description  
Features  
■ Choice of 8 latches or 8 D-type flip-flops in a single  
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.  
package  
■ 3-STATE bus-driving outputs  
■ Full parallel-access for loading  
■ Buffered control inputs  
■ P-N-P inputs reduce D-C loading on data lines  
The eight latches of the DM74LS373 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.  
The eight flip-flops of the DM74LS374 are edge-triggered  
D-type flip flops. On the positive transition of the clock, the  
Q outputs will be set to the logic states that were set up at  
the D inputs.  
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 or flip-flops. That is, the old data can be  
retained or new data can be entered even while the outputs  
are OFF.
