SN74LS74AM Dual D-Type Positive Edge-Triggered Flip-Flop
The SN74LS74AM from ON Semiconductor is a high-performance, dual D-type positive edge-triggered flip-flop integrated circuit, designed to operate as a versatile memory storage element. It is a fundamental component used in various digital systems, including counters, registers, and control circuits. The device is part of the low-power Schottky (LS) family, which is well-known for its balance between speed and power consumption, making it suitable for a wide range of applications.
This flip-flop features two independent D-type flip-flops, each with its own set of inputs and outputs. The inputs include a direct clear (CLR\), a direct set (SET\), a clock (CLK), and a data input (D). The outputs are the Q and Q\ (complementary) terminals. The backslash (\) notation indicates active-low signals, meaning that the flip-flop will respond to a low logic level on these inputs.
The SN74LS74AM is designed to trigger on the rising edge of the clock signal, ensuring precise timing for the data captured at the D input. Once the clock signal transitions from low to high, the value present at the D input is stored and reflected at the Q output. The SET\ and CLR\ inputs can be used to override the clock and immediately set or clear the flip-flop, which is useful for initialization or reset purposes.
This device is fabricated with ON Semiconductor's advanced technology, which provides the reliability and performance required for modern electronic systems. It is available in a variety of package types, including SOIC and PDIP, allowing for flexible integration into PCB designs. The SN74LS74AM operates over a wide supply voltage range, typically from 4.75V to 5.25V, and features a typical power dissipation of only 20mW per flip-flop, making it an energy-efficient choice for battery-powered devices.
With its robust design and versatile functionality, the SN74LS74AM is an essential component for designers who require reliable and efficient flip-flops for their digital applications. Whether you're building complex computing systems or simple timing circuits, the SN74LS74AM from ON Semiconductor is a reliable choice that delivers consistent performance and quality.
