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.). Absolute maximum ratings (Ta = 25°C) BA7649A
Parameter Power supply voltage Allowable current Operating temperature Storage temperature Symbol VCC Pd Topr Tstg Limits 13.5 1100∗
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.
