| LM556/NE556 Dual Timer • Replaces Two LM555/NE556 Timers • Operates in Both Astable And Monostable Modes • High Output Current • TTL Compatible • Timing From Microsecond To Hours • Adjustable Duty Cycle • Temperature Stability Of Per °C • Precision Timing • Pulse Shaping • Pulse Width Modulation • Frequency Division • Traffic Light Control • Sequential Timing • Pulse Generator • Time Delay Generator • Touch Tone Encoder • Tone Burst Generator Internal Block Diagram The LM556/NE556 series dual monolithic timing circuits are a highly stable controller capable of producing accurate time delays or oscillation. The LM556/NE556 is a dual LM555. Timing is provided an external resistor and capacitor for each timing function. The two timers operate independently of each other, sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA. 14-DIP 14-SOP 2001 Fairchild Semiconductor Corporation LM556/NE556 Absolute Maximum Ratings TA = 25°C Parameter Value Unit Supply Voltage Lead Temperature soldering 10sec TLEAD Power Dissipation Operating Temperature Range LM556/NE556 TOPR 0 ~ + 70 Storage Temperature Range TSTG - 65 ~ + 150 LM556/NE556 Electrical Characteristics TA = 25°C, VCC = 5 ~ 15V, unless otherwise specified Parameter Supply Voltage Supply Current *1 two timers low state Timing Error *2 monostable Initial Accuracy Drift with Temperature Drift with Supply Voltage Control Voltage Threshold Voltage Threshold Current*3 Trigger Voltage Trigger Current Reset Voltage*5 Reset Current Low Output Voltage High Output Voltage Rise Time of Output Fall Time of Output Discharge Leakage Current Matching Characteristics*4 Initial Accuracy Drift with Temperature Drfit with Supply Voltage Timing Error astable *2 Initial Accuracy Drift with Temperature Drift with Supply Voltage Symbol VCC Conditions VCC = 5V, RL = ∞ VCC = 15V, RL = ∞ Min.
