NTE1658
Integrated Circuit
Television Tuner Band Selector
Description:
The NTE1658 is an integrated circuit in a 9–Lead SIP type package designed for electronically tuning
television sets. This IC is used for producing the VHF channel “L” band power supply/VHF channel
“H” band power supply/UHF channel power supply for tuner and the CATV power supply according
to the band select signal of 2 inputs.
Functions:
D VHF “L” Band Power Supply Output
D VHF “H” Band Power Supply Output
D UHF Power Supply Output
D CATV Power Supply Output
Features:
D 2 Inputs and 4 Outputs
D Output Low Saturation Voltage: 250mV Typ (IO = 60mA)
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
