BD3843FS,BD3841FS
BD3843FS is a function switch IC with two 6ch (9ch for BD3841FS) inputs. It can independently control outputs of 2 systems:
2ch REC output (3ch for BD3841FS) and 1ch line output. Therefore, it is can be used for 2nd room entertainment and 2nd
source recording. BD3843FS has excellent cross-talk characteristics between channels and selectors. Low distortion, and
low noise are realized by a basic pattern layout.
AV receivers, home theater systems, mini-audio systems, and TVs.

1) 2 room entertainment / 2 source recording.
2) 6ch volume LSI BD3813KS/BD3815KS can be controlled simultaneously by the serial control bus.
3) 7ch volume LSI BD3816K1, BD3817KS with BD3843FS can be controlled simultaneously by the serial control bus.
4) 14ch input is available by combining 2chips (BD3843FS and BD3841FS).
5) Excellent cross-talk characteristics between channels by basic pattern layout.
6) Built-in buffer amplifier.
7) 2-line serial control bus (for both 3.3V and 5V).
8) Operated by single and dual power sources.
Even in the specified range of Power Supply Voltage, applying voltage only to the VCC side may cause
an excessive current may cause permanent damage to the IC.
When starting up power supplies, VEE and VCC should be powered on simultaneously, or VEE first followed by VCC.
Reduced by 8 mW/℃ over 25℃ (BD3843FS), when installed on the standard board (size: 70 x 70 x 1.6mm).
Reduced by 7.7 mW/℃ over 25℃ (BD3841FS), when installed on the standard board (size: 70 x 70 x 1.6mm).
