SA556
Overview
The Nx556 and Sx556 devices provide two independent timing circuits of the NA555, NE555, SA555, or SE555 type in each package. These circuits operate in an astable or monostable mode with external resistor-capacitor (RC) timing control.
- Two precision timing circuits per package
- Astable or monostable operation
- TTL-compatible output can sink or source up to 200mA
- Active pullup or pulldown
