Technical Specifications: The HD74LVC574ATELL operates with a supply voltage range of 1.65V to 5.5V and has a propagation delay of approximately 3-5 ns, depending on the supply voltage and load conditions. The output drive capability is typically ±24mA. It is commonly available in a 20-pin TSSOP (Thin Shrink Small Outline Package). Data is latched on the positive-going edge of the clock (CLK) input. The output enable (OE) input controls the output state; when OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state.
