LM556

Dual Timer

General Description

Features

n Direct replacement for SE556/NE556

n Timing from microseconds through hours

The LM556 Dual timing circuit is a highly stable controller ca-

pable of producing accurate time delays or oscillation. The

556 is a dual 555. Timing is provided by an external resistor

and capacitor for each timing function. The two timers oper-

ate independently of each other sharing only V_CCand

ground. The circuits may be triggered and reset on falling

waveforms. The output structures may sink or source

200mA.

n Operates in both astable and monostable modes

n Replaces two 555 timers

n Adjustable duty cycle

n Output can source or sink 200mA

n Output and supply TTL compatible

n Temperature stability better than 0.005% per ˚C

n Normally on and normally off output

Applications

n Precision timing

n Pulse generation

n Sequential timing

n Time delay generation

n Pulse width modulation

n Pulse position modulation

n Linear ramp generator
