HD3SS214IZQER Application Field and Working Principle

Interface is a term which describes the connection between two devices. It implies specific input and output devices which makes it possible for the devices to communicate. Of the many different types of interfaces, analog switches are one of the most versatile and are used in a vast variety of applications. Special purpose analog switches are ideal for several applications such as communication, instrumentation, industrial, power, and automated test equipment. A special purpose analog switch is the HD3SS214IZQER from TI. This paper will discuss the application fields and the working principle of the HD3SS214IZQER.The HD3SS214IZQER is an integrated circuit that provides a single-pole double-throw (SPDT) non-latching switch for ultra-low power applications. It is especially suitable for applications in which power consumption needs to be minimized, e.g., battery-powered applications. It features an ultra-low quiescent current of only 0.04 µA, and a power-on reset (POR) circuit. It is designed to switch ultra-low voltage signals, such as 0.9–3.3 V CMOS, TTL and LVCMOS, while consuming virtually no current. It is available in a small, 7-pin chip-scale package and is ideal for hand-held and mobile applications.The HD3SS214IZQER is often used as an isolation switch between two different logic signals, or as a signal selector or multiplexer between several logic signals. It can also be used as a level shifter, or as an analog multiplexer to select between several analog inputs. Its low on-resistance makes it ideal for signal routing in high-speed applications.The HD3SS214IZQER has two power-supply pins, called Supplies (Vcc) and Grounds (GND). The other five pins are in-pins, out-pins, select-pins, enable-pins and reset-pins. The Supplies and Grounds pins provide the power and ground supply needed for the operating of the switch. The in-pins are used to connect the signal inputs to the switch for signal routing. The out-pins are used to connect the signal output of the switch. The select-pins control the direction of signal flow between the in-pins and out-pins. The enable-pins control the enable and disable switching of the switch. The reset-pins are used to reset the switch.The working principle of the HD3SS214IZQER is relatively simple. Power is supplied to the Supplies and Grounds pins. The voltage on the Supplies pin is typically around 3.3 V, which is sufficient for switching ultra-low voltage signals. The in-pins are connected to the signal inputs for signal routing and the out-pins are connected to the signal outputs. The select-pins are then used to control the direction of signal flow between the in-pins and out-pins. The enable-pin is used to enable and disable the switch. The reset-pin is used to reset the switch. When the switch is enabled, signals flowing through the in-pins will be routed through the selected out-pin.In summary, the HD3SS214IZQER is a special purpose analog switch specifically designed for ultra-low power applications. It is ideal for applications such as communication, instrumentation, industrial, power, and automated test equipment. It is an ultra-low current switch which switches ultra-low voltage signals while consuming virtually no current. The HD3SS214IZQER is operated by providing power to the Supplies and Grounds pins, connecting the in-pins and out-pins to the signal inputs and outputs, and controling the direction of signal flow by the select-pin and enable-pin. The reset-pin is used to reset the switch.
