LM556 Datasheet

DUAL TIMER


 
DESCRIPTION
 
   The UTC LM556 dual monolithic circuit is a highly
stable controller capable of producing accurate delays
or oscillation. The UTC LM556 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.  


 
 FEATURES
 
*High current driver capability(=200mA)
*Adjustable duty cycle
*Timing from µSec to Hours
*Temperature stability of 0.005%/°C
*TTL compatible
*Operates in both Astable and Monostable modes
