SN74HC574N IC Octal D-Type Flip-Flop Positive-Edge Trigger 3-State

From the shop's description

SN74HC574N IC Octal D-Type Flip-Flop Positive-Edge Trigger 3-State The SN74HC574N is a highly versatile digital integrated circuit from Texas Instruments that combines eight identical D-type flip-flops in a single package. Each flip-flop captures and stores the data present at its inputs on the positive edge of the clock signal, allowing synchronous digital systems to reliably latch 8-bit parallel data. Its design follows high-speed CMOS technology, providing a wide operating voltage range and low power consumption. Unlike simple latches, the SN74HC574N ensures data transfer only occurs on clock transitions, making it suitable for controlled timing applications in microprocessor data registers, buffers, and other storage elements. The inclusion of 3-state outputs permits the outputs to be placed in a high-impedance state, allowing multiple devices to share a common bus without interference. This bus-oriented architecture aids in building complex digital systems where resources are shared or multiplexed. Packaged typically in a 20-pin Dual In-Line Package (PDIP) for through-hole mounting, this component supports robust and flexible circuit design in both hobbyist and industrial contexts. Its balanced performance characteristics make it a foundation in digital buffering, register storage, and interface tasks where stable, synchronous 8-bit data handling is needed. Features: Wide operating voltage range from 2 V to 6 V. Eight edge-triggered D-type flip-flops in one IC. 3-state noninverting outputs for bus sharing. Positive-edge clock triggering ensures synchronous data capture. Low power consumption with typical ICC ≤ 80 µA. Balanced outputs with typical propagation delays ~22 ns. Bus-structured pinout for ease of interfacing. CMOS input and output compatibility.
