BA7607

Multimedia ICs Video signal switcher BA7607 / BA7607F The BA7607and BA7607F are switching ICs developed for use in VCRs. Each contains three two-channel analog multiplexers. As two of the switches have sync-tip clamp inputs and the other one has non-clamped inputs these ICs are ideal for switching audio, video and chroma signals. Applications Video cassette recorders and televisions Features 1) Three 2-input / 1-output switches (two with sync-tip clamped inputs, the other one non-clamped). 2) 5V power supply. 3) Low power consumption (62.5mW Typ.). 4) Excellent frequency characteristics (10MHz, 0dB Typ.). 5) Wide dynamic range (clamped input: 2.9VP-P Typ., non-clamped input: 3.0VP-P Typ.). 6) Fast switching speed (50ns Typ.).
