TRI-STATE 4-Bit D-Type Register  
É
General Description  
This four-bit register contains D-type flip-flops with totem-  
pole TRI-STATE outputs, capable of driving highly capaci-  
tive or low-impedance loads. The high-impedance state and  
increased high-logic-level drive provide these flip-flops with  
the capability of driving the bus lines in a bus-organized sys-  
tem without need for interface or pull-up components.  
To minimize the possibility that two outputs will attempt to  
take a common bus to opposite logic levels, the output con-  
trol circuitry is designed so that the average output disable  
times are shorter than the average output enable times.  
É
Features  
Y
Gated enable inputs are provided for controlling the entry of  
data into the flip-flops. When both data-enable inputs are  
low, data at the D inputs are loaded into their respective flip-  
flops on the next positive transition of the buffered clock  
input. Gate output control inputs are also provided. When  
both are low, the normal logic states of the four outputs are  
available for driving the loads or bus lines. The outputs are  
disabled independently from the level of the clock by a high  
logic level at either output control input. The outputs then  
present a high impedance and neither load nor drive the bus  
line. Detailed operation is given in the truth table.  
TRI-STATE outputs interface directly with system bus
