NTE926
Integrated Circuit
Quad Timer
Description:
The NTE926 quad timer is a monolithic timing device which can be used to produce four independent
timing functions. The NTE926 output sinks current. This highly stable, general purpose controller
can be used in a monostable mode to produce accurate time delays–from microseconds to hours.
In the time delay mode of operation, the time is precisely controlled by one external resistor and one
capacitor. A stable operation can be achieved by using two of the four timer sections.
The four timer section in the NTE926 are edge–triggered, therefore, when connected in tandem for
sequential timing applications, no coupling capacitors are required. Output current capability of
100mA is provided in both devices.
