NTE1409 & NTE1409N
Integrated Circuit
Electronic Channel Selector
Description:
The NTE1409 is an electronic channel selector integrated circuit in a 24鈥揕ead DIP type package
capable of selecting up to 16 channels. The output terminals are design to permit direct driving of
LEDs or neon tubes.
It consists of a Clock Oscillator circuit, a Channel Up and Down circuit, a Channel skip circuit, a 4 bit
Up and Down Counter circuit, a 1鈥?6 Decoder circuit and a 16 channel Output Buffer circuit.
