These devices provide two independent timing circuits of the NA555, NE555, SA555, or SE555 type in each package. These circuits can be operated in the astable or the monostable mode with external resistor-capacitor (RC) timing control. The basic timing provided by the RC time constant can be controlled actively by modulating the bias of the control-voltage input.

Features:

1. Two Precision Timing Circuits Per Package
2. Astable or Monostable Operation
3. TTL-Compatible Output Can Sink or Source up to 150 mA
4. Active Pullup or Pulldown
5. Designed to Be Interchangeable With Signetics NE556, SA556, and SE556

Package includes:

1xNE556 dual timer ic
