• Supply Voltage: 2V to 6V

Product Overview:

The SN74HC574APW boasts a robust design that ensures reliable operation over a wide range of supply voltages, from 2V to 6V. Each flip-flop has independent data (D), clock (CLK), set (S), and reset (R) inputs, as well as Q and Q̅ outputs. The clock triggering occurs at a voltage level and is not directly related to the rise and fall times of the clock pulse.

Furthermore, the outputs can be placed in either a high-impedance state or a low-impedance state, which is determined by the output enable (OE) input, making it suitable for interfacing with bus-structured systems. The flip-flops are triggered on the low-to-high transition of the clock input while the set and reset inputs are active low, which ensures that the IC is flexible enough to be used in a variety of timing applications.

With its wide operating temperature range of -40°C to +85°C, the SN74HC574APW is designed for robust performance in challenging environments. The device is packaged in a space-saving 20-TSSOP configuration, making it ideal for compact PCB layouts in modern electronic applications.

Whether used in microprocessor systems, registers, data storage, or any other digital logic application that requires high-speed, reliable data storage, the SN74HC574APW from Texas Instruments is an excellent choice for designers and engineers seeking a high-quality, versatile flip-flop IC.
