Quiet Series錚?Octal Latch with 3-STATE Outputs
General Description
The ACQ/ACTQ573 is a high-speed octal latch with buff-
ered common Latch Enable (LE) and buffered common
Output Enable (OE) inputs. The ACQ/ACTQ573 is func-
tionally identical to the ACQ/ACTQ373 but with inputs and
outputs on opposite sides of the package. The ACQ/ACTQ
utilizes Fairchild鈥檚 Quiet Series錚?technology to guarantee
quiet output switching and improved dynamic threshold
performance. FACT Quiet Series錚?features GTO錚?output
control and undershoot corrector in addition to a split
ground bus for superior performance.
