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.

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.

Applications

Video cassette recorders and televisions

BA7649AF属于集成电路（IC） > 信号开关，多路复用器，解码器。罗姆半导体集团制造生产的BA7649AF信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
