The SN74LS423NSR is a high-performance, dual retriggerable monostable multivibrator manufactured by Texas Instruments. This integrated circuit (IC) is designed to generate precise timing pulses and is a part of the 7400 series logic family. With its retriggerable feature, the device allows for the extension of output pulse duration with the application of additional input triggers.

Key Features

• Voltage Range: The SN74LS423NSR operates at a voltage range of 4.75V to 5.25V, making it compatible with TTL power levels.
• Output Pulse Width Control: The width of the output pulse can be controlled by connecting an external resistor and capacitor to the timing pins.
• Retriggerable Functionality: This IC can be retriggered by applying a pulse to the input before the current pulse has expired, thus extending the output pulse without any false triggering.
• Direct Clear Input: A direct clear input is provided to allow immediate termination of the output pulse on demand.
• High-Speed Operation: The SN74LS423NSR is capable of high-speed operation, which is essential for timing-critical applications.
• Package Type: It comes in an SOP (Small Outline Package) with a 14-pin configuration, suitable for surface mounting (NSR suffix).

Applications
