Analog switches, multiplexers, and demultiplexers are all basic components of analog-to-digital circuitry. They are typically used in a variety of applications, ranging from communication systems design, power control circuitry to consumer electronics. The ISL43210IHZ-T7A is a quad differential analog switch and multiplexer (ASM) with two independent channels, and is part of a larger family of switch and multiplexer devices. It’s designed primarily as an analog signal switching/multiplexing device, but can be used in a variety of other applications, such as fan speed control, power management and protection circuitry, circuit isolation, and signal isolation.

The ISL43210IHZ-T7A features two independent, differential switches with both true and complementary logic outputs for added versatility. The analog switch has low on resistance and is ESD tolerant, with an integrated ESD protection diode. It’s suitable for use in high-speed data applications, where clock speeds can reach up to 1GHz. It’s also made to meet the requirements of low voltage and low power consumption applications.

The ISL43210IHZ-T7A features a selectable internal 8-mS flight-time to ensure good isolation between the output and the inputs. This design allows for easier design integration, since the 8-mS flight-time ensures that the input signal will not distort or affect the output signal during the switch cycle. The maximum output current of the ISL43210IHZ-T7A is 4mA. It also has an adjustable current limit of up to 8mA.

The ISL43210IHZ-T7A is capable of switching between two input signals, or alternatively multiplexing between two signals, in either case of which the result is an output signal with the desired logic or switching level. The device internally controls both the switching time and the output current limit, enabling the analog switch to operate safely at high speeds. Additionally, ISL43210IHZ-T7A features a selectable output source/sink current limit from 200uA to 8mA.

The ISL43210IHZ-T7A operates on an operating voltage range from 3.3V to 5V. Additionally, the device can operate in either single supply or dual supply configuration, with a single supply voltage from 3.15V to 5V. Its input and output range is from VSS-0.3V to VDD+0.3V.

The ISL43210IHZ-T7A is simple to use, requiring no external connections or components, just a power supply connection (VDD) and two logic signals (ON and OFF) to control the channels. The device is protected against ESD voltage up to 2000V, ensuring protection against transients on the analog lines or digital supply lines, and supporting full system design isolation requirements.

The ISL43210IHZ-T7A is ideal for applications that require fast switching between two differential signal sources, such as source switching and multiplexing applications, fan control, power management and protection circuitry, and signal isolation circuitry. With its combined features of low power consumption, high speed switching, and adjustable current limiting, the ISL43210IHZ-T7A is an ideal solution for a variety of analog applications.
