Overview
The SN74LS123ML1 is a dual retriggerable monostable multivibrator from the ON Semiconductor LS series. It features DC triggering via active-high or active-low gated logic inputs, allowing pulse width control through external resistance and capacitance values. The device includes an overriding clear function to terminate output pulses and is compensated for VCC and temperature variations. It supports retriggering for extended output pulses up to a 100% duty cycle.
Feature Summary
- DC triggered by active-high or active-low gated logic inputs
- Retriggerable for very long output pulses with up to 100% duty cycle
- Overriding clear input terminates output pulse immediately
- Compensated for VCC and temperature variations
Applications
- Pulse generation circuits
- Timing delay applications
- Debouncing switches
- Frequency division
Procurement Notes
Verify the specific suffix ML1 against official datasheets to confirm package type and temperature range. Ensure compatibility with existing circuit designs regarding trigger logic levels and timing components. Cross-reference with manufacturer documentation for any updates on lead times or availability status.
Selection Notes
Select this component when dual independent monostable circuits are required in a low-power Schottky TTL format. Consider its retriggerability feature for applications requiring pulse extension. Verify that the external RC components meet the desired timing specifications within the operating voltage and temperature ranges.
Part Context
This part belongs to the SN74LS123 family of dual retriggerable monostable multivibrators. It is manufactured by ON Semiconductor (formerly Fairchild Semiconductor) and is part of the standard 74LS logic series. The device is designed for general-purpose timing and pulse shaping applications in digital systems.
Replacement Considerations
Direct substitutes include SN74LS123 variants from other manufacturers such as Texas Instruments or Motorola. Ensure pinout compatibility and electrical characteristics match before substitution.
