54ACTQ541  
Quiet Series Octal Buffer/Line Driver with TRI-STATE®  
Outputs  
General Description  
Features  
n Non-inverting buffers  
The ’ACTQ541 is an octal buffer and line driver with  
TRI-STATE outputs designed to be employed as a memory  
and address driver, clock driver, or bus-oriented transmitter/  
receiver.  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
n Flow-through pinout for ease of PC board layout  
The ’ACTQ541 is similar to the ’ACTQ244 while providing  
flow-through architecture (inputs on opposite sides from out-  
puts). This pinout arrangement makes this device especially  
useful as an output port for microprocessors, allowing ease  
of layout and greater PC board density.  
n Non-inverting TRI-STATE outputs  
n TTL compatible inputs  
n CMOS power consumption  
n Output source/sink 24 mA  
n Standard Microcircuit Drawing (SMD) 5962-9682901  
The ’ACTQ541 utilizes NSC Quiet Series technology to  
guarantee quiet output switching and improved dynamic  
threshold performance. FACT Quiet Series  
features  
GTO output control and undershoot corrector in addition to  
a split ground bus for superior ACMOS performance.
