The MAX459CQH-D is a special purpose analog switch designed for a variety of applications. It is part of the MAX family of analog switches, including standard logic, motor control and integrated field-programmable logic (FPL).

The MAX459CQH-D is an 8-bit switch with a 25-MHz maximum switching rate and can reduce a wide range of power consumption by up to 35 percent. It comes in two different packages, a compact 8-pin SOIC and a 4.2mm-x-4.2mm, 6-pad µMAX plastic package. The switch has eight independent single-pole double-throw (SPDT) or dual-pole single-throw (DPST) switches with separate control signals and an input resistance of 150 Ohms.

The MAX459CQH-D\'s wide voltage range (1.8V to 5.5V) and low on-resistance (8mOhms) make it ideal for battery-powered or low-power applications such as portable medical and hand-held electronics. It is also used in several types of analog switching applications, including multiplexers, sample-and-holds, analog-to-digital converters, and voltage-controlled oscillators (VCOs).

The MAX459CQH-D\'s wide operating temperature range (-55°C to 125°C) makes it suitable for a diverse range of environments. Its wide common mode rejection ratio (CMRR) also makes it suitable for industrial, automotive, and high-reliability applications.

The MAX459CQH-D\'s on-state resistance is determined by its internal clamping structure. Its on-state resistance is usually between 4mOhms and 8mOhms. The device is designed to provide an accurate and repeatable switch actuation with low jitter. The device also has a power control system that provides low-power switching at very low clock rates (up to 1MHz). It is also designed to switch without noise or glitching, hence the common-mode rejection ratio is typically greater than 80 dB at frequencies up to 1.2MHz.

The MAX459CQH-D\'s static current draw is typically less than 1 microamp and its microamp leakage current is typically less than 100 nanoamps. The switch\'s average switching current is typically less than 200 microamps.

In summary, the MAX459CQH-D is an ideal analog switch for various applications due to its wide operating temperature range, low power consumption, wide voltage range, low on-resistance, and high common-mode rejection ratio. Its versatility, reliability, and low power consumption are ideal for battery-powered and low power applications.
