( DataSheet : www.DataSheet4U.com ) TD74BC574P/F TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TD74BC574P,TD74BC574F Octal D-Type Flip-Flop with 3-State Outputs (Non-Inverted) The TD74BC574P/TD74BC574F is a high-speed 8-bit flip-flop fabricated with silicon gate Bi-CMOS technology. It achieves the high-speed operation equivalent to the FAST family while maintaining the Bi-CMOS low-power dissipation. The TD74BC574P/F is a non-inverting flip-flop. Each bit is individually controlled by a clock input (CK) and an output enable input (OE). When the OE input is high, all eight outputs are in the high-impedance state, which facilitates the interface with bus lines. All inputs are equipped with resistors and diodes to protect against Electrostatic Discharge (ESD).
