ON Semiconductor DM74LS123N Dual Retriggerable Monostable Multivibrator
The ON Semiconductor DM74LS123N is a highly stable device that generates accurate time delays or oscillation. As part of the 74LS series, this dual retriggerable monostable multivibrator is designed to operate with exceptional reliability and performance, making it an ideal choice for a wide range of applications in digital systems. The DM74LS123N is capable of producing two completely independent timing circuits within a single package, which can be triggered by either a transition or a pulse longer than the designed output pulse width.
With its retriggerable feature, the output pulse duration can be extended by applying additional triggers, which provides flexibility and precision in timing applications. The output pulse duration is controlled by an external resistor (R) and capacitor (C), allowing users to customize the timing interval to suit their specific requirements. The pulse duration can range from a few nanoseconds to several milliseconds, providing a versatile solution for timing needs.
The DM74LS123N is fabricated with Low Power Schottky technology, which ensures reduced power consumption without sacrificing speed. This technology also contributes to the multivibrator's fast propagation delay times and high noise immunity, characteristics that are essential for maintaining signal integrity in complex digital circuits.
The device features a 14-pin dual-in-line package (DIP), which is widely used and easily integrated into various electronic assemblies. It operates over a wide voltage range of 4.75V to 5.25V and includes features such as individual clear and output pulse shaping, as well as direct triggering from the leading or trailing edge of the input pulse.
ON Semiconductor's commitment to quality and performance is evident in the DM74LS123N, making it a reliable component for applications such as timers, pulse generation, sequence generation, and event counting. Its robust design and versatile functionality make it an essential part of any digital logic system requiring precise timing control.
Overall, the DM74LS123N is a testament to ON Semiconductor's reputation for producing high-quality, dependable integrated circuits that meet the stringent requirements of modern electronic devices.
