NTE NTE1409

NTE1409 & NTE1409N
Integrated Circuit
Electronic Channel Selector
Description:
The NTE1409 is an electronic channel selector integrated circuit in a 24–Lead 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 1–16 Decoder circuit and a 16 channel Output Buffer circuit.
Features:
D LED Direct Drive
D Low Power Consumption
D Up to 16 Channel Selections
D Internal Schmitt Trigger Circuit
D Power ON Initial Channel Set
D TV, Radio, etc. Channel Selection Use.
D Can be Used with NTE1758 Direct Address Remote Control System
