General-purpose CMOS Logic IC Series (BU4S,BU4000B Series)

High Voltage CMOS Logic ICs Analog Switch

●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, BU4052BCis configured with two 4 channels,BU4053BC series is configured with three 2 channels, BU4551B series is configured with four 2 channels, and switches applicable for each channel are turned on according to digital signals of control terminal. Even if the logic 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
