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 interference.
