1 / 5 page 1 Multimedia ICs Video signal switcher BA7649A / BA7649AF The BA7649A and BA7649AF are five-channel analog multiplexers (the IN5 pin can be used a mute input) designed for use in video cassette recorders. They feature large dynamic range, and wide operating frequency range, and have sync-tip inputs which are ideal for switching video signals. •Applications Video cassette recorders and televisions •Features 1) 5-input / 1-output switches. 2) Built-in mute (the IN5 pin can be use a mute input). 3) Sync-tip clamp inputs. 4) Wide operating supply voltage range (4.5V to 13.0V). 5) Low power consumption (48mW Typ.). 6) Excellent frequency characteristics (10MHz, 0dB Typ.). 7) Wide dynamic range (3.5VP-P Typ.). 8) Low interchannel crosstalk ( – 65dB Typ., f = 4.43MHz). 9) DIP / SOP 14 pin package. •Absolute maximum ratings (Ta = 25°C) BA7649A Parameter Symbol Unit VCC 13.5 V 1100∗ mW °C °C – 25 ~ + 75 – 55 ~ + 125 Topr Tstg Pd Limits ∗ Reduced by 11.0mW for each increase in Ta of 1°C over 25°C.
