Part Description: LM556 NE556 Dual Timer

Part Details: LM556/NE556 Dual Timer Features Description · Replaces Two LM555/NE556 Timers The LM556/NE556 series dual monolithic timing circuits · Operates in Both Astable And Monostable Modes are a highly stable controller capable of producing accurate · High Outpu t Current time delays or oscillation. The LM556/NE556 is a dual · TTL Compatible LM555. Timing is provided an external resistor and capaci- · Timing From Microsecond To Hours tor for each timing function. The two timers operate inde- · Adjustable Duty Cycle pendently of each other, sharing only VCC and ground. The · Temperature Stability Of 0.005% Per °C circuits may be triggered and reset on falling waveforms.The output structures may sink or source 200mA. Applications· Precision Timing 14-DIP · Pulse Shaping 14-SOP · Pulse Width Modulation· Frequency Division· Traffic Light Control· Sequential Timing· Pulse Generator 1 1 · Time Delay Generator· Touch Tone Encoder· Tone Burst Generator Internal Block Diagram Rev. 1.0.0 ©2001 Fairchild Semiconductor Corporation LM556/NE556 Absolute Maximum Ratings (TA = 25°C) Parameter Symbol Value Unit Supply Voltage VCC 16 V Lead Temperature (soldering 10sec) TLEAD 300 °C Power Dissipation PD 600 mW Operating Temperature Range T LM556/NE556 OPR 0 ~ + 70 °C
