8 DIP
The NE555/I is a highly stable controller capable of producing accurate
timing pulses. With monostable operation, the time delay is controlled
by one external and one capacitor. With astable operation, the frequency
and duty cycle are accurately controlled with two external resistors and
one capacitor.

Notes:
1. Supply current when output is high is typically 1mA less at VCC = 5V
2. Tested at VCC = 5.0V and VCC = 15V
3. This will determine maximum value of RA + RB for 15V operation, the max. total R = 20MΩ, and for 5V operation the
max. total R = 6.7MΩ
APPLICATION CIRCUIT
NE555 (KA555)
SINGLE TIMER
APPLICATION NOTE
The application circuit shows astable mode.
Pin 6 (threshold) is tied to Pin 2 (trigger) and Pin 4 (reset) is tied to VCC (Pin 8).
The external capacitor C1 of Pin 6 and Pin 2 charges through RA, RB and discharges through RB only.
In the internal circuit of the NE555 one input of the upper comparator is the 2/3 VCC (∗R1 =R2=R3, another input if it
If it is connected Pin 6.
As soon as charging C1 is higher than 2/3 Vcc, discharge transistor Q1 turns on and C1 discharges to collector of
transistor Q1.
Therefore, the flip-flop circuit is reset and output is low.
One input of lower comparator is the 1/3 VCC, discharge transistor Q1 turn off and C1 charges through RA and RB.
Therefore, the flip-flop circuit is set and output is high.
So to say, when C1 charges through RA and R1 output is high and when C1 discharges through RB output is low.
The charge time (output is high) T1 is 0.693 (RA+RB) C1 and the discharge time (output is low) T2 is 0.693 (RB C1).
CC
(In VCC-1/3V
= 0.693)
VCC-2/3VCC
Thus the total period time T is given by
T=T1 +T2 = 0.693 (RA +2RB) C1.
Then the frequency of astable mode is given by
f=

T

The duty cycle is given by

If you make use of the NE556 you can make two astable modes.
NE555 (KA555)
SINGLE TIMER
Astable Operation
The NE555 can free run as a mulitivibrator by triggering itself; refer to Fig.2. The output can swing from VDD to GND and have
50 duty cycle square wave. Less than 1% frequency deviation can be observed, over a voltage range of 2 to 5V. f-1/1.4RC

Monostable Operation
The NE555 can be used as a one-short, i.e. monostable multivibrator. Initially, because the inside discharge transistor is on
state, external timing capacitor is held to GND potential. Upon application of a negative TRIGGER pulse pin 2, the intern
discharge transistor is off state and the voltage across the capacitor increases with time constant T = RAC and OUTPUT
goes to high state. When the voltage across the capacitor equals 2/3VCC the inner comparator is reset by THRESHOLD
input and the discharge transistor goes to on state, which in turn discharges the capacitor rapidly and drives the OUTPUT
to its low state.
