NTE1758
Integrated Circuit
CMOS, 27 Command TV Remote Control Transmitter
Description:
The NTE1758 is a CMOS integrated circuit in a 16–Lead DIP type package designed for controlling
the transmitter of remote control systems for TV sets, etc. By using this device in combination with
the NTE1759 receiver control IC, a direct channel control system can be obtained. When an infrared
emitting diode is used as a transmitter element, this system will be very stable against any interfer-
ence.
Features:
D Capable of Transmitting 27 Commands:
