• High-speed CMOS logic technology
• Wide operating temperature range

Multivibrators Applications

• Pulse timing generation
• Frequency division
• Timing delays
• Waveform shaping

Multivibrators Procurement Notes

Verify the specific suffix against official documentation, as generic part numbers often lack critical packaging or environmental details. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for active production status or obsolescence notices before finalizing procurement plans.

Multivibrators Selection Notes

Select this component when dual independent monostable functions are required in a compact surface-mount package. Ensure the 2 V to 6 V supply voltage aligns with system power rails. Verify that the 25 ns propagation delay meets timing constraints and that the -55°C to 125°C temperature range suits the operational environment.

Multivibrators Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It is functionally related to other monostable multivibrators like the SN74HC123 but offers dual channels in a single package. The SOIC-16 footprint allows for space-efficient PCB layouts compared to through-hole alternatives.
