HCF4556M013TR is a member of the High-Performance Controlled Impedance Family of devices, which are logical signal switches, multiplexers and decoders individually.

HCF4556M013TR is a Quad single-pole double throw (SPDT) analog switch with built-in controlled input/output impedance. It is designed to control an analog signal within the IC and features a low total harmonic distortion (THD), a wide dynamic range and high channel-to-channel Crossover distortion (XO) isolation performance.

The HCF4556M013TR has a high-density array of SPDT switches with a total package size of 4x4 mm and a typical power consumption of less than 1mW, making it suitable for handheld telecommunication systems and other space-crunched application.

The SPDT switch consists of four independent switches that can be switched at a switching speed of about 190ns with TTL logic signals. These switches are electrically equivalent and therefore offer symmetrical electrical characteristics for each pair.

Furthermore, the HCF4556M013TR offers low on resistance, low non-linear, flat switch distortion and low power consumption. Thus, it provides the ability to efficiently handle analog signals in applications where high-speed switching is necessary.

The application of the HCF4556M013TR is a low-voltage, wide-band analog signal switch designed to minimise distortion and improve the performance of high-bandwidth systems. It is specifically designed to reduce noise and distortion caused by crosstalk and interferences, thus allowing the HCF4556M013TR to provide a more reliable performance in applications that handle large bandwidths and require a high level of integration.

In terms of its working principle, the HCF4556M013TR operates on a low-voltage CMOS logic supply. This logic supply is connected to the device\'s control pins, which input the control signals to the on/off control of the SPDT switch. The device has four unique inputs (A1, A2, B1, B2) and one common output (P). When any one of the control inputs is asserted, the switch connects the corresponding input to the output, and when the control input is de-asserted, the switch connects the output to the other input.

The HCF4556M013TR has four SPDT switches and each one has its own logic level control input and its own logic level control output. When signals are applied to the input, they are used to drive the SPDT switches. When the signals change, the SPDT switches react correspondingly, thus allowing the signal to either bypass or route to the output.

In conclusion, the HCF4556M013TR is a member of the High-Performance Controlled Impedance Family of devices and is an ideal choice for applications requiring low distortion and high channel-to-channel isolation. This device features a low total harmonic distortion (THD), a wide dynamic range and high channel-to-channel Crossover distortion (XO) isolation performance, and can be used in signal switching and routing applications. Furthermore, its working principle is based on low-voltage CMOS logic supply and its four independent SPDT switches.
