HEF4051BT-Q100,118

The HEF4051BT-Q100 is a 8 x 1 Analog Multiplexer / Demultiplexer that can control more than one digital and analog signals in electronic designs. The device is composed of 8 identical channels, each channel includes 3 terminals which are: Channel Selection (S), Input (I) and Output (O). It has a single chip that can be used to switch either one of 8 input signals (multiplexing) or 8 output signals (demultiplexing). It is part of the 4000B range of general purpose CMOS circuit families.

The 118 application field refers to the HEF4051BT-Q100 performance in analog switching, multiplexing and demultiplexing applications. The device is primarily attractive in the applications which require a low on-state resistance and low power consumption. The device operates with low power of max 10 mW. The low-voltage CMOS logic and low quiescent on-state current make the device particularly suitable for use with low-voltage sources such as LCDs and CCDs.

The working principle of HEF4051BT-Q100 is based on digital logic control and analog signals. The digital control is used to switch the multiplexer to desired state and the analog signals can be connected to either inputs (I) or the Output (O). It is a digital device, so it requires a logic voltage for the device to switch and the output is a combination of analog signals. The device has an on resistance of 250W which ensures low power consumption and high signal to noise ration. The device supports high-speed buffered logic inputs, so the switching speed is faster. Moreover, the HEF4051BT-Q100 has a wide supply voltage of 2.7V to 10V and is compliant with ESD standards.

In short, the HEF4051BT-Q100 is a 8 x 1 Analog Multiplexer / Demultiplexer device and can be used in applications like switching, multiplexing, and demultiplexing with features such as low power, low on-state resistance and wide supply voltage range. The device is suitable for use with both digital and analog signals, so it is ideal for transferring high speed data signals and making connections in analog applications. Furthermore, the device has an excellent transient performance and high reliability which ensures a long life span of the device.
