Functional DescriptionFunctional Description Octal Schmitt D-Type Flip-Flop with 3-State Outputs 2. 2. 2. 2. GeneralGeneralGeneralGeneral The 74VHCV574FT is advanced high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input (OE). When the OE input is high, the eight outputs are in a high impedance state. Input pin have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCV574FT is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, etc. Note: Output in off-state. 3. 3. FeaturesFeatures 3. 3.
