UHF/VHF TUNER IC
The TA1281F, TA1281FA, and TA1281FN are TV tuner ICs TA1281F
which integrate on a single chip IF amp, a mixer/
oscillator for VHF band and cable TV, together with a
mixer/oscillator for UHF band.
Supply voltage of 5V helps lower power dissipation from
the set. Compact 16-pin SSOP makes the tuner more
compact.
