The HD74HCT574FPEL is an octal D-type flip-flop with three-state outputs manufactured by Renesas Electronics America. This device features a clock (CLK) input and an output enable (OE) input. When OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state. The data is transferred to the outputs on the positive-going edge of the clock pulse.

Additional Details

The HD74HCT574FPEL consists of eight D-type flip-flops with a common clock and output enable. The data is loaded into the flip-flops on the positive-going edge of the clock pulse. The outputs are enabled when the output enable (OE) input is low and are in the high-impedance state when OE is high. The device operates from a 4.5V to 5.5V supply voltage and is available in a flat package (FP). The operating temperature range is -40°C to +85°C.
