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

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:

Applications:
