NTE1658
Integrated Circuit
Television Tuner Band Selector
Description:
The NTE1658 is an integrated circuit in a 9鈥揕ead SIP type package designed for electronically tuning
television sets. This IC is used for producing the VHF channel 鈥淟鈥?band power supply/VHF channel
鈥淗鈥?band power supply/UHF channel power supply for tuner and the CATV power supply according
to the band select signal of 2 inputs.
