NTE876
Linear Integrated Circuit
LED Flasher/Oscillator

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.

Packaged in an plastic 8-Lead mini-DIP, the NTE876 will operate over the extended consumer temperature range of -25°C to +70°C. It has been optimized for low power drain and operation from weak batteries so that continuous operation life exceeds that expected from battery rating.

Timing capacitors will generally be of the electrolytic type, and a small 3V rated part will be suitable
for any LED flasher using a supply up to 6V. However, when picking flash rates, it should be remembered that some electrolytics have very broad capacitance tolerances, for example -20% to +100%.

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 8? 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
