The latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data satisfy- ing the input timing requirements is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the HIGH impedance state. The ACQ/ACTQ373 utilizes Fairchild Quiet Series™ technology to guarantee quiet output switching and improve dynamic threshold performance. features GTO™ output control and undershoot corrector in addi- tion to a split ground bus for superior performance. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
