Description:

The NTE876 is monolithic oscillator specifically designed to flash Light Emitting Diodes. By using the timing capacitor for voltage boost, it delivers pulses of 2 or more volts to the LED while operating on a supply of 1.5V or less. The circuit is inherently self–starting, and requires the addition of only a battery and capacitor to function as an LED flasher.

Features:

● Operation over one year from one C size flashlight cell

● Bright, high current LED pulse

● Minimum external parts

● Internal Timing Resistor

● Internal LED Current Limiting Resistor

● Low voltage operation, from just over 1V to 5V

● Low current drain, averages under 0.5mA during battery life

● Powerful as an oscillator directly drives an 8Ω speaker

Applications:

● Finding flashlights in the dark, or locating boat mooring floats

● Sales and advertising gimmicks

● Emergency locators, for instance on fire extinguishers

● Toys and novelties: e.g., Siren for toy fire engine

● Electronic applications such as trigger and sawtooth generators

● Warning indicators powered by 1.4V to 200V
