NTE1738
Integrated Circuit
TV Remote Control Receiver
Description:
The NTE1738 is a 29鈥揻unction remote鈥揷ontrol receiver circuit manufactured by aluminum鈥揼ate
CMOS technology for use in television receivers, audio equipment, and the like using infrared for
transmission. It enables direct control of 12 functions at the receiver.

D
Three Analog Functions 鈥?Volume, Brightness and Color Saturation 鈥?are Independently
Controlled to 64 Stages by Three 6鈥揃it D/A Converters.
D
12 Instructions are Controlled at the NTE1738 Receiver, as well.
D

Application:
D
Remote鈥揅ontrol Receiver for TV or other Applications
Function:
The NTE1738 is designed to decode and execute instructions after three successive receptions of
the identical instruction code, providing a good noise immunity. Instructions comprise direct selection
of 16 channels, channel position high and low, color saturation high and low, normalization of volume,
brightness and color saturation, sound mute on and off, TV main power on and off, and output CALL
on and off.
In addition, 12 functional instructions can be entered from the receiver.
