●Description
BU4066BC series ICs each contain 4 independent switches capable of controlling either digital or analog signals.
BU4051BC / BU4052BC / BU4053BC / and BU4551B series ICs are analog selectable composite multiplexer/demultiplexer.
BU4051BC series is configured with 8 channels, BU4052BC is configured with two 4 channels,BU4053BC series is
configured with three 2 channels, BU4551B series is configured with four 2 channels, and s witches applicable for each
channel are turned on according to digital signals of control terminal. Even if the log ic amplitude (VDD-VSS) of the control
signal is small, signals of large amplitude (VDD-VEE) can be switched.

●Features

1) Low power consumption

2) Wide operating supply voltage (3[V]~18[V])

3) High input impedance

4) L-TTL2 input and LS-TTL1 can be driven directly.

5) Applicable channel switches can be turned “ON” and “OFF” by the digital control signal.

6) Small control voltage (VDD-VSS) can control signals of large amplitude (VDD-VEE).

7) Linearity with excellent transfer characteristics

●Use
This product is used as the switch and chopper modulation circuit of analog and digital signals.
Since ON resistance of each switch is low, the product can be connected to low impedance circuit.
The product can be used as ON/OFF switch and changeover switch of high-speed lines without degradi ng analog signals
such as voice and images.
