SN74HCS174-Q1

The SN74HCS174-Q1 is a high-speed CMOS hex D-type flip-flop manufactured by Texas Instruments, designed for reliable data storage and synchronization in digital systems. It features six independent D-type flip-flops, each with a clock input (CLK), data input (D), and complementary outputs (Q and Q̅). The device operates with a supply voltage range of 2.0 V to 6.0 V, making it compatible with both low-voltage and standard logic families. Its low power consumption and high noise immunity ensure stable performance in demanding environments. This component incorporates advanced HCS (High-Speed CMOS) technology, offering propagation delays as low as 15 ns at 5 V, enabling fast signal processing without sacrificing power efficiency. Each flip-flop includes a master-slave architecture that ensures edge-triggered operation on the rising edge of the clock signal, allowing precise control over data capture and transfer. The outputs are capable of driving up to 10 LSTTL loads, providing robust interfacing with other digital circuits. The SN74HCS174-Q1 is qualified to AEC-Q100 Grade 1 standards, making it suitable for automotive applications where reliability, thermal stability, and long-term durability are critical. It supports industrial temperature ranges from –40°C to +125°C, ensuring consistent operation under extreme conditions. Additionally, the device features ESD protection on all inputs and outputs, enhancing resistance to electrostatic discharge during handling and operation. Common applications include data latching, frequency division, waveform generation, and timing control in automotive electronics such as engine control units (ECUs), infotainment systems, and body control modules. It is also used in industrial automation, consumer electronics, and communication equipment where reliable sequential logic functions are required. The package options include SOIC, TSSOP, and HVSON, offering flexibility in board design and assembly processes. With its combination of speed, low power, and robustness, the SN74HCS174-Q1 serves as an essential building block in modern digital systems requiring precise control over data flow and timing synchronization.
