The ISL84780IV is a monolithic CMOS analog multiplexer, part of the industry-leading FLEX I/O family of Standard Logarithmic ICs from Renesas. This IC features a 1:64, 16-bit-wide, non-volatile analog multiplexer that provides fast switching and low power consumption. The ISL84780IV is capable of switching 1.5V to 3.6V logic signals, is temperature and power supply insensitive, and meets the 32-bit requirements for the typical-delay specification for automotive applications.

The ISL84780IV provides an ideal solution for high performance, low-power analog multiplexing. The device can switch 1.5V to 3.6V and is temperature and power supply insensitive. The device includes a one-time settable, non-volatile 16-bit latch, which allows the user to configure the device to their application-specific needs. The ISL84780IV features two 16-bit non-volatile multiplexers with a separate, independently adjustable sequential sampling switch. The device also supports three different speed modes (fast, slow, and maximum operating speeds) that are individually selectable to accommodate different application requirements.

The ISL84780IV is designed to meet the needs of high performance, low-power analog multiplexing applications. The device features a non-volatile 1:64 multiplexer with a single pin to configure the multiplexer. This one-time programming, which sets the multiplexer’s device-speed selection from 16 to 32-bit, enables the device to reduce input levels to the internal logic gates, thereby reducing power consumption. The device also supports multiplexer latency options for applications requiring a wide range of input-sampling times.

The device includes a main control register, a shift register, and programmable control registers. The ISL84780IV is designed to integrate seamlessly into existing designs, allowing for flexible low-power multiplexer control. The device can be controlled via the SPI, I2C, and SMBus interfaces. The ISL84780IV provides both user-programmable and automatic sequencing capability in order to optimize the power consumption. The device supports up to 32 different registers and can be used to program multiplexer channels, speed modes, and various other features.

The ISL84780IV is an ideal solution for applications requiring analog multiplexing in an ultra-low-power mode. Its flexibility, combined with a wide range of features, makes the device suitable for a wide range of applications. Additionally, the ISL84780IV is RoHS compliant, making it an ideal choice for automotive, industrial and medical applications. By using the ISL84780IV, engineers can quickly design and implement a low-power analog multiplexer into their designs with minimal effort.
