UTC NE556
DUAL TIMER
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC NE556 dual monolithic circuit is a highly
stable controller capable of producing accurate delays
or oscillation. The UTC NE556 is the dual of UTC
NE555; timing is provided an external resistor and
capacitor for each function. The two timers operate
independently of each other, sharing only Vcc and
GND. The circuits may be triggered and reset on falling
wave forms. The output structures may sink or source
200mA.
