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

and reset on falling wave forms. The output structures may sink or

source 200mA.
