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:
Direct Replacement for 556 Timers
Replaces Two 555 Timers
Timing from Microseconds through Hours
Operates in both Astable and Monostable Modes
Adjustable Duty Cycle
Output can Source or Sink 200mA
Output and Supply TTL Compatible
Temperature Stability better than 0.005% per °C
Normally On and Normally Off Output
Available in Three Types:
