Product Summary

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.

  • Direct replacement for 556 timers
  • Replaces 2 555 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 3 types: NTE978 14--lead DIP; NTE978C 14--lead DIP (CMOS); NTE978SM SOIC--14 (surface)
  • Supply voltage, VCC: +18V
  • Power dissipation, PD:* 1620mW
  • Operating temperature range, TA: 0° to +70°C
  • Storage temperature range, Tstg: --65° to +150°C
  • Lead temperature (during soldering, 10sec Max), TL: +260°C
