LM556/NE556
Dual Timer
Features
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 0.005% Per

Description
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 capaci-
tor for each timing function. The two timers operate inde-
pendently of each other, sharing only V
CC
and ground. The
circuits may be triggered and reset on falling waveforms.
The output structures may sink or source 200mA.
Applications
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
