The CBTW28DD14AETJ silicon monolithic integrated circuit is a special purpose interface analog switch. It is manufactured using an advanced CMOS technology, which enables it to switch analog signals and to provide a high level of accuracy and reliability over a wide temperature range. The device is designed for applications in automotive, industrial, and consumer segments as well as for portable systems.

The CBTW28DD14AETJ features two CMOS switches controlled independently by two digital signal lines. The switches are configured in the DD14A configuration, which means that each switch has one control signal line, two digital control inputs, and two analog signal inputs. The signal lines and control inputs are TTL/CMOS compatible and capable of operating over a wide input voltage range. The analog signal path is designed to achieve high signal integrity, low leakage, and low distortion.

The CBTW28DD14AETJ is designed to operate in a wide temperature range from -20°C to +85°C. It is available in a variety of package sizes and can be used with a variety of external components including resistors, capacitors, and protection diodes. The device has an ESD (electrostatic discharge) protection level of Class 2 per JEDEC Standard JESD22-B106C.

The working principle of the CBTW28DD14AETJ is based on the conduction of current when the digital control input is in logic high state and the conduction being postponed when the digital input is in logic low state. The input impedance of the analog signals is very high, in the order of megohms. The analog signals are switched at a very low voltage level, typically 0.7V. The switching speed is also very fast, typically less than 8ns.

The CBTW28DD14AETJ is an ideal device for Analog to Digital (A/D) and Digital to Analog (D/A) conversion, power control, interface circuitry, and protection applications. Its low power consumption makes it suitable for portable applications and its small form factor allows it to be used in tight spaces. Its wide temperature range and high signal integrity makes it suitable for use in automotive and industrial applications.
