BU4551B Datasheet PDF - ROHM Semiconductor

●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
