CBMG739 2.5 Ω、低压、三线式串行控制、双路4通道矩阵开关

CBMG739 is a CMOS, dual 4-channel analog matrix switch with a serial controlled three wire interface. The conduction resistance matching between switches is strict, and the conduction resistance curve is very flat throughout the entire signal range.

CBMG739 adopts a three wire serial interface and is compatible with SPI ™、 QSPI ™、 MICROWIRE ™ Compatible with some DSP interface standards. By using the output of the shift register OUT, several such devices can be connected in a daisy chain form. When powered on, the internal shift register is all zero, and all switches are in the off state.

When turned on, the conductivity of each switch is the same in both directions, making this device suitable for both multiplexing and demultiplexing applications. Each switch is connected or disconnected through a separate position, so this device can also be configured in the form of a switch matrix, where any or all of the eight switches can be closed or disconnected at any time. The input signal range can be extended to the power supply voltage range.

All channels adopt a first open and then close switch to prevent instantaneous short circuits when switching channels.
