UTCLM556 LINEAR INTEGRATED CIRCUIT
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
APPLICATIONS
*Precision timing.
*Pulse generator, shaping.
*Time delay generator.
*Sequential timing.
*Pulse width modulation.
*Traffic light control.
*Touch tone encoder.
*Tone burst generator.

Note 1: Supply current when output is high is typically 1mA less at Vcc 5V.
Note 2: Tested at Vcc=5V and Vcc=15V.
Note 3: This will determine the maximum value of RA+RB for 15V operation, The maximum total is R=20M, and
for 5V operation the maximum total is R=6.6M.
Note 4: As reset voltage lower, timing is inhibited and then the output goes low.
Note 5: Matching parameters refer to the difference between performance parameters of each timer section in the
monostable mode.
