Product Attributes

Part Number: NE555 Description: The NE555 is a highly stable device for generating accurate time delays or oscillation. Features: Timing from microseconds through hours Operates in both astable and monostable modes Adjustable duty cycle TTL compatible Output can source or sink up to 200mA Temperature stability of 0.005% per °C Applications: Pulse generation Sequential timing Time delay generation Pulse width modulation Pulse position modulation Linear ramp generator Low frequency oscillators (For reference only)

Introduce this Module:

The 555 timer IC was introduced in the year 1970 by Signetic Corporation and gave the name NE 555 timer. It is in a single 8 pin. Apart from its applications as a monostable multivibrator and A stable Multivibrator, DC-DC Converters, digital logic probes, waveform generators, analog frequency meters measurement, temperature control, volt regulators, etc.

Some Core Parameters of the Module:

SPECIAL FEATURES :

● High Current Drive Capability (200mA)

● Adjustable Duty Cycle

● Temperature Stability of 0.005%/℃

● Timing From μSec to Hours

● Turn off Time Less Than 2μSec

NE555 Pinout Connections:

● Pin 1 - Ground (GND) This pin is connected to the circuit ground.

● Pin 2 - Trigger (TRI) Active low trigger input that starts the timer.

● Pin 3 - Output (O/P) Timer output pin.

● Pin 4 - Reset (RES) A low voltage (less than 0.7V) the reset pin will cause the output pin to go low. This input should remain connected to Power Supply when not used.

● Pin 5 - Control voltage (CON): Used to adj the threshold voltage if required. This should be left dis-connected if the function is not required. A 0.01uF Capacitor to Ground can be used in electrically noisy circuits.

● Pin 6 - Threshold (TRE) In both a stable and monostable mode the voltage across the timing capacitor is monitored through the Threshold input. When the voltage at this input rises above the threshold value the output will go from 1 to 0.

● Pin 7 – Discharge (DIS) Output pin that is used to discharge the timing capacitor.

● Pin 8 – Supply voltage (VCC) A positive supply voltage terminal. The supply voltage range is usually between +5V to +15V.

What you refer to as a low power 555 is not a 555. It is a CMOS 555, and has major, major differences in characteristics. It's drive is weak, it can go from 2VDC to 18VDC, and basically is just enough different from a classic 555 as to be considered a different part, as in many cases they are not interchangeable, mostly due to drive characteristics and the resistors used to set the 1/3 and 2/3 voltage points. As with the 555, there are many companies making the CMOS 555, with different part numbers. Radio Shack sells the TLC555, the TI version of the chip. Due to minor variations in process the CMOS chips can have variations in performances and speeds, but mostly they are interchangeable with each other, just like a standard 555 is usually interchangeable between manufacturers. The 558 is completely different altogether, and was only inspired by the 555. In no way is it a quad 555, unlike the 556, which has a 1 to 1 pinout corespondent and is a true dual 555.
