Contek Microelectronics 

NE556

LINEAR INTEGRATED CIRCUIT

DUAL TIMER

DESCRIPTION

The Contek NE556 dual monolithic circuit is a highly

stable controller capable of producing accurate delays

or oscillation. The Contek NE556 is the dual of Contek

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 mSec 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.
