The ISL43741IRZ is a family of interface analog switches and multiplexers that use CMOS technology and operate from a single 3V to 5.5V power supply. This family of switches and multiplexers features 1:8 multiplexing and signal switching. The application field for this device is primarily for signal multiplexing, signal routing and signal switching. The power supply voltage range for the ISL43741IRZ is from 2.3 volts to 5.5V which makes it ideal for applications requiring low power consumption.

The ISL43741IRZ is externally protected with diode protection per input and output to limit the maximum current to a safe level. The maximum output current is 30mA and the maximum input current is 30mA. The on resistance range provided by the family is 0.9 ohms to 7.5 ohms, with a maximum on resistance of 8.2 ohms. The operating temperature range is -40˚C to +125˚C which makes it suitable for use in a variety of different environments.

The switching time of the ISL43741IRZ is 1 μs, which is considerably faster than most other multiplexers. The propagation delay of the switch is typically 7 μs while the rise and fall times are 2 ns and 5 ns, respectively. The jitter of the instruction cycle time is 0.8 μs and the signal-to-noise ratio (SNR) is typically 70 dB.

The device also features ESD protection up to 2 kV (human body model). This level of ESD protection makes it suitable for use in portable mobile devices as it can protect against electrostatic events such as inadvertently touching the device or shorting the device when it is not in use.

The input power is TTL/CMOS compatible and the family includes a product that has two-track input capability. The family includes switch products with two, four, six and eight channel inputs. In addition, the family includes multiplexer products with four, six, and eight channel outputs.

The ISL43741IRZ family also provides users with the ability to customize their switching requirements. The family includes switches and multiplexers with various enable disabling options such as active low, active high and enable/disable via instruction. The device also includes various pin configurations and packages to meet any application requirements.

The working principle of the ISL43741IRZ is simple and involves the transfer of electrical signals from the input pins to the output pins. When the device is enabled, the device will shift the input to the output and when the device is disabled, the device will not allow the signal to be transferred. The device has an enable input pin which can be used to control the switching by either asserting a logic high (1) or a logic low (0).

The ISL43741IRZ family is an ideal solution for a variety of digital and analog applications requiring fast switching, higher integration and easy customizability. This family of switches and multiplexers offer low power consumption and a wide range of power supply voltages, making them suitable for both mobile and industrial systems. The extra protection of ESD protection up to 2kV and flexible enable/disable pins make the device one of the most reliable solutions in the market.
