NTE7004
Integrated Circuit
Electronic Channel Select System Control
Description:
The NTE7004 contains CPU/PLL–excluded peripheral circuits such as band switch, +5V power sup-
ply (with RST), sync detector, low–pass filter for color TV/VCR frequency synthesizer channel select
system use.
Functions:
D Band Switch (2–Input, 4–Output)
D Video Signal, Flyback Pulse, AFT Output–Used Detection of Tuning Mode and Horizontal
Sync Mode
D +5V Power Supply, with RST Output (for CPU)
D OP Amp for Low–Pass Filter (for Frequency Synthesizer)
Features:
D The Band Switch Truth Table can be changed in a short period of time at the user’s option.
D The Band Switch is of PNP output type which need not be driven externally.
D The OP Amp for Low–Pass Filter is excellant in pulse response because of it’s High–Imped-
ance Input Pin.
