74ACTQ18823 General Description
The ACTQ18823 contains eighteen non-inverting D-type flip-flops with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. A buffered clock (CP), Clear (CLR), Clock Enable (EN) and Output Enable (OE) are common to each byte and can be shorted together for full 18-bit operation.
The ACTQ18823 utilizes Fairchild's Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector for superior performance.
