Key Features
- Dual independent monostable multivibrator channels enable two separate one-shot pulse generation functions in a single 16-pin IC
- LV/LV-A logic family supports wide 1.65V to 5.5V supply range for mixed-voltage and low-power digital systems
- Externally programmable pulse width via resistor and capacitor allows flexible one-shot timing from nanoseconds to milliseconds
- Pb-free SOIC-16 (R-PDSO-G16) package with 50pF load capacitance simplifies surface-mount PCB design and assembly
Applications
The SN74LV221ADG4 is used in digital pulse generation, signal debouncing, time delay insertion, and pulse-width shaping circuits where precise one-shot timing is required in low-voltage systems. It is well suited for microcontroller interface circuits, switch debounce networks, watchdog timeout generators, and communication protocol timing in battery-powered consumer electronics and IoT devices. System designers also use it in power sequencing control and event detection circuits where a clean, retriggerable pulse of defined duration must be generated from a digital trigger signal.

Frequently Asked Questions
What are the key specifications of the SN74LV221ADG4?
The SN74LV221ADG4 is a dual monostable multivibrator with 2 channels, 2 data inputs per channel, a 50pF load capacitance rating, and a maximum output low current (IOL) of 12mA, housed in a 16-pin SOIC package. It belongs to the LV/LV-A logic family and operates across a wide supply voltage range of 1.65V to 5.5V.
How is the output pulse width of the SN74LV221ADG4 set?
The output pulse width of the SN74LV221ADG4 is set by an external resistor and capacitor connected to the timing pins of each channel. The pulse width is proportional to the RC time constant, giving designers full flexibility to tune one-shot timing from very short pulses (nanoseconds) to longer delays (milliseconds), independently for each of the two channels.
What applications is the SN74LV221ADG4 suited for?
This IC is suitable for switch debouncing, pulse stretching, time delay generation, signal conditioning, power supply sequencing, and watchdog circuit design. Its dual-channel architecture and wide supply voltage range make it especially useful in battery-powered IoT devices, embedded microcontroller systems, and industrial control logic where low-voltage one-shot timing is required.
Is the SN74LV221ADG4 RoHS compliant and what does the G4 suffix mean?
Yes, the SN74LV221ADG4 is Pb-free with JESD-609 Code e4, confirming RoHS compliance and lead-free construction. The G4 suffix in Texas Instruments part numbering indicates the device meets the Green (halogen-free) and RoHS material compliance standards, making it suitable for environmentally compliant manufacturing and export to global markets.
