ALD7555 / ALD7556 CMOS Analog RC Timers

Advanced Linear Devices ALD7555 / ALD7556 CMOS Analog RC Timers offer improved performance in speed, leakage currents, supply current, stability, temperature voltage stability, and discharge output drive compared to NE555 / NE556, SE555, TLC555, and ICM7555 / ICM7556 timers. The ALD7555 and ALD7556 feature high input impedance, which allows smaller timing capacitors and a longer timing cycle, high speed, and low power dissipation for battery-operated environments. This feature also offers reduced supply current spikes, allowing smaller and lower cost decoupling capacitors. These single/dual monolithic analog RC timing circuits offer a guaranteed low operating supply voltage of 2V to 10V, and a high discharge sinking current of 80mA at 5V.
