SJM188BIC is an all metal-sealed, surface mount, high speed analog switch IC. It has a total of 8 channels and each channel has a single pole, double throw switch. The typical application range includes multiplexers, demultiplexers, and some low-to-moderate speed logic switching applications. Because SJM188BIC has such a high switching speed, they are commonly used in cellular phones, PDAs, portable computers, and fiber-optic networking.

The basic operation of the SJM188BIC is pretty straightforward. Each channel has two independent switches that are activated by a control line (called S1 and S2). A high voltage level is applied to the control lines and the switch is turned on. To turn off the switch, a low voltage is applied to the control lines. The number of active switches is determined by the logic level of the control lines. The SJM188BIC can also be configured in such a way that it can be used as a demultiplexer or multiplexer.

As for specifications, the switching speed of the SJM188BIC is quite impressive. It offers a high switching speed of 10MHz and an almost nonexistent power consumption of 6.2µA. The on-chip driver circuits enable stable switching operation even at high speed bus speeds. As for the allowable range of power supply voltages, the minimum voltage is 2.0V and the maximum voltage is 6.0V.

The package of the SJM188BIC is a small leadless chip carrier, meaning that the chip can be soldered directly onto the printed circuit board. This allows for easier installation and lots of savings in space and cost. On top of that, it has a good amount of tolerance to ESD (electrostatic discharge) of up to 4kV.

In conclusion, the SJM188BIC is an excellent analog switch IC that is suitable for a wide range of applications. Its fast switching speed and low power consumption make it ideal for use in cellular phones, PDAs, portable computers, and fiber-optic networking. Its high tolerance to ESD makes it a very robust part. Finally, the leadless package of SJM188BIC makes it an attractive choice for designers who need to save space and cost.
