ADVANCED LINEAR DEVICES ALD7556
The ALD7555/ALD7556 timers are high performance single/dual mono- • Saves battery power lithic analog RC timing circuits. They offer significantly upgraded perfor- • Eliminates additional buffer mance in speed, leakage currents, supply current, stability, temperature • Smaller, lower cost capacitor voltage stability, and discharge output drive when compared to SE555/ • Extended range of time constants NE555,ICL7555, TLC555, and ICM7555. The ALD7555/ALD7556 offer the benefits of high input impedance, thereby allowing smaller timing capacitors and a longer timing cycle; high speed; low power dissipation for battery operated environment; reduced supply current spikes, allowing smaller and lower cost decoupling capacitors.
