UTCNE556 LINEAR INTEGRATED CIRCUIT
DUAL TIMER
DESCRIPTION
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.
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.
