NTE978/NTE978C/NTE978SM  
Integrated Circuit  
Dual Timer  
Description:  
The NTE978 series dual timing circuit is a highly stable controller capable of producing accurate time  
delays or oscillation. The NTE978 is a dual NTE955. Timing is provided by an external resistor and  
capacitor for each timing function. The two timers operate independently of each other sharing only  
VCC and GND. The circuits may be triggered and reset on falling waveforms. The output structures  
may sink or source 200mA.  
Features:  
D Direct Replacement for 556 Timers  
D Replaces Two 555 Timers  
D Timing from Microseconds through Hours  
D Operates in both Astable and Monostable Modes  
D Adjustable Duty Cycle  
D Output can Source or Sink 200mA  
D Output and Supply TTL Compatible  
D Temperature Stability better than 0.005% per °C  
D Normally On and Normally Off Output  
D Available in Three Types:  
NTE978  
14–Lead DIP  
NTE978C  
14–Lead DIP (CMOS)  
NTE978SM SOIC–14 (Surface Mount)  
Applications:  
D Precision Timing  
D Pulse Generation  
D Sequential Timing  
D Time Delay Generation  
D Pulse Width Modulation  
D Pulse Position Modulation  
D Linear Ramp Generator
