NE555L-D08-T

UNISONIC TECHNOLOGIES CO., LTD NE555 LINEAR INTEGRATED CIRCUIT SINGLE TIMER  DESCRIPTION The UTC NE555 is a highly stable timer integrated circuit. It can be operated in both Astable and Monostable mode. With monostable operation, the time delay is precisely controlled by one external and one capacitor. With a stable operation as an oscillator the frequency and duty cycle are both accurately controlled with two external resistors and one capacitor.  FEATURES *High current driver capability (=200mA). *Adjustable duty cycle. *Timing from s to hours. *Turn off time less than 2s. *Operates in both astable and monostable modes. ■ ORDERING INFORMATION Ordering Number Lead Free NE555L-D08-T -  Halogen Free NE555G-D08-T NE555G-S08-R Package Packing DIP-8 SOP-8 Tube Tape Reel MARKING DIP-8 www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd SOP-8 1 of 7 QW-R106-001.G NE555 LINEAR INTEGRATED CIRCUIT  PIN CONFIGURATION  BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R106-001.G NE555  LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 16 V Power Dissipation PD 600 mW Junction Temperature TJ +125 °C Operating Temperature TOPR -20 ~ +85 °C Storage Temperature TSTG -40 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.

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 dischages through RB only. In the internal circuit of UTC NE555N , one input of the upper comparator is at voltage of 2/3VCC (R1=R2=R3),another input is connected to Pin 6.As soon as C1 is charging to higher than 2/3VCC, transistor Q1 is turned ON and discharge C1 to collector voltage of transistor Q1. Therefore, the flip-flop circuit is reset and output is low. One input of lower comparator is at voltage of 1/3Vcc, discharge transistor Q1 turn off and C1 charges through RA and RB. Therefore, the flip-flop circuit is set output high. That is, when C1 charges through RA and RB, output is high and when C1 discharge 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. VCC In VCC - 1 3 2 3 VCC = 0.693 VCC T1=0.693×(RA+RB)×C1 Thus the total period time T is given by T=T1+T2=0.693(RA+2RB)×C1. T2=0.693×RB×C1 Then the frequency of astable mode is given by f= 1 T 1.44 = (RA + 2RB)×C1 The duty cycle is given by D.C.  T2 T UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw  RB RA  2RB . 5 of 7 QW-R106-001.G NE555 TYPICAL CHARACTERISTICS Supply Current,ICC (mA) Low-Level Output Voltage vs Low-Level Output Current 10 7 4 VCC=5V TA=-55℃ 2 1 0.7 0.4 TA=25℃ TA=125℃ 0.2 0.1 0.07 0.04 0.02 Low-Level Output Voltage vs Low-Level Output Current 10 7 4 VCC=10V 2 TA=25℃ 1 0.7 0.4 TA=-55℃ TA=125℃ 0.2 0.1 0.07 0.04 0.02 0.01 0.01 1 Low-Level Output Voltage,VOL (V) Low-Level Output Voltage,VOL (V) Low-Level Output Voltage,VOL (V) Voltage Drop,(VCC-VOH) (V)  LINEAR INTEGRATED CIRCUIT 4 20 40 70 100 7 10 2 Low-Level Output Current,IOL (mA) 1 2 4 20 7 10 40 70 100 Low-Level Output Current,IOL (mA) Low-Level Output Voltage vs Low-Level Output Current 10 7 4 VCC=15V TA=-55℃ 2 1 0.7 0.4 TA=25℃ 0.2 TA=125℃ 0.1 0.07 0.04 0.02 0.01 1 2 4 7 10 20 40 70 100 Low-Level Output Current,IOL (mA) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 6 of 7 QW-R106-001.G NE555 LINEAR INTEGRATED CIRCUIT UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein.
