General Description  
Features  
Y
Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
Guaranteed pin-to-pin skew AC performance  
Combines the ’245 and the ’280 functions in one  
package  
The ’ACQ/’ACTQ657 contains eight non-inverting buffers  
with TRI-STATE outputs and an 8-bit parity generator/  
checker. Intended for bus oriented applications, the device  
combines the ’245 and the ’280 functions in one package.

The ’ACQ/’ACTQ utilizes NSC Quiet Series technology to  
guarantee quiet output switching and improved dynamic  
threshold performance. FACT Quiet SeriesTM features  
GTOTM output control and undershoot corrector in addition  
to a split ground bus for superior performance.
