BU4053B Datasheet

Multiplexer Switch ICs


The BU4053B , BU4053BCF, and BU4053BCFV are multiplexers / demultiplexers capable of selecting and combining analog signals and digital signals in a 2 ch ´ 3 configuration. Inhibit signals and control signals are used to turn on the switch corresponding to each of the channels. In addition, even if the logical amplitude (VDD-VSS) of the control signal is low, signals with a large amplitude (VDD-VEE) can be switched. Also, as each switch has a low ON resistance, it can be connected to a low impedance circuit. BU4053B Features • Low power consumption• Wide operating supply voltage (3[V]~18[V])• High input impedance• L-TTL2 input and LS-TTL1 can be driven directly.• Applicable channel switches can be turned “ON” and “OFF” by the digital control signal.• Small control voltage (VDD-VSS) can control signals of large amplitude (VDD-VEE).• Linearity with excellent transfer characteristics
