Multimedia ICs
Video signal switcher
BA7613N / BA7613F
The BA7613N and BA7613F are three-channel analog multiplexers with built-in mute, 6dB amplifier and 75Ω driver.
The ICs designed for use in video cassette recorders, and feature a large dynamic range and wide operating frequency range. Sync-tip clamp inputs make this an ideal switch for video signals.
