This document describes the features and characteristics of the 74HC/HCT564 octal D-type flip-flop, including positive-edge triggering, 3-state outputs, and inverting outputs. This product is suitable for bus-oriented applications.
The document is a product specification for the 74HC/HCT564 integrated circuit. It details that these are high-speed Si-gate CMOS devices pin compatible with low power Schottky TTL (LSTTL). The chip features an octal D-type flip-flop configuration with separate data inputs and common clock and output enable lines.

|---|---|
| Input capacitance | 3.5 pF |
| Power dissipation capacitance per flip-flop (Cpp) | 27 pF |
| Output capability | Bus driver |
When OE is LOW, outputs are available; when HIGH, they go to high impedance OFF-state.
Yes, but it has inverting outputs.
