Overview
The LA7916 contains CPU/PLL-excluded peripheral circuits such as switch, +5V power supply (with RST), sync detector, low-pass filter for color TV/VCR frequency synthesizer channel select system use.

FEATUREs
• The band switch truth table can be changed in a short period of time at the user’s option.
• The band switch is of pnp output type which need not be driven externally.
• The operational amplifier for low-pass filter is excellent in pulse response because of its high-impedance input pin.

Functions
• Band switch (2-input 4-output).
• Video signal, flyback pulse, AFT output-used detection of tuning mode and horizontal sync mode.
• +5V power supply, with RST ouput (for CPU).
• Operational amplifier for low-pass filter (for frequency synthesizer).
