Product Description

The NE555 SMD IC is a surface-mount version of the NE555 timer IC, a popular integrated circuit used in timing and oscillator applications. Here's a brief overview:

NE555 Timer IC: The NE555 is a versatile timer IC that can be configured to perform various timing functions, including astable (oscillator) and monostable (one-shot) operations. It consists of comparators, flip-flops, and a voltage divider network, allowing it to generate precise timing signals based on external components such as resistors and capacitors.

Features:

Supply Voltage (Vcc): The NE555 SMD IC operates with a maximum supply voltage of 18V, making it suitable for a wide range of applications.
Input Voltage Level: It is TTL-compatible, meaning it can interface with other TTL logic devices. The input voltage level is typically equal to the supply voltage (Vcc).
Output Capability: The NE555 can sink or source up to 200mA of current, making it capable of driving small loads directly.
Timing Range: It offers a wide timing range, from microseconds to hours, depending on the configuration and values of external components connected to it.
Timing from microseconds to hours
A stable or monostable operation
Adjustable duty cycle
TTL compatible output can source or sink up to 200 mA
“Green” Molding Compound (No Br, Sb)
Lead Free Finish/ RoHS Compliant

Applications: The NE555 SMD IC finds applications in various electronic circuits, including:

Timer Circuits: It is commonly used to generate precise time delays and pulses in applications such as timers, oscillators, and PWM (Pulse Width Modulation) circuits.
Pulse Generators: The NE555 can generate square wave pulses of varying frequencies and duty cycles, making it useful in applications like clock generation, frequency synthesis, and waveform generation.
Control Circuits: It is employed in control systems for tasks such as triggering, timing, and sequencing operations in electronic devices and systems.
Voltage Regulation: In some configurations, the NE555 can be used to implement simple voltage regulators and voltage-controlled oscillators (VCOs).

The NE555 SMD devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset, and the output goes low. When the output is low, a low impedance path is provided between discharge (DISCH) and ground. The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of 5V to 15V. With a 5-V supply, output levels are compatible with TTL inputs.
