Interface - Analog Switches, Multiplexers, Demultiplexers can be found in various electronic systems and products. Among them, MAX313LCUE+T is one of the most widely used products in this area. The components of this product offer various useful characteristics and features, including improved switching, low power dissipation, wide operating temperature range, low leakage current, and high on-state conduction.

The MAX313LCUE+T is an advanced CMOS multiplexer and a CMOS analog switch. It is designed to interface to low voltage analog and digital circuits. The product contains two 8-channel multiplexer/demultiplexer, one 2-channel multiplexer/demultiplexer and an 8-channel analog switch. It is designed to operate over the full -40°C to +105°C temperature range.

The MAX313LCUE+T allows low noise operation with its low on-state resistance, low output capability offset, and typically low leakage current. The on-state resistance of this multiplexer parallel switch can be up to 3.2 kΩ, depending on the selected multiplexer/switch polarity-of-use and on/off current. At +6 V, over the -40°C to +105°C temperature range, the leakage current is typically less than 0.2 µA.

The device is also able to support no power-up glitches since the outputs remain high impedance during power-down. The switching speeds can be increased by the provision of NOMOS-type logic pulses from a PNP transistor source.

The MAX313LCUE+T can be used in a wide array of applications, including industrial control, remote monitoring, portable and home automation, instrumentation, motor control, computer and communications equipment. The product can also be used in 3-wire datalinks, personal computers and server data transmission, as well as target board/modular applications.

The MAX313LCUE+T also features low on-state power dissipation. The analog switch supports versatile control functions for stationary, portable, and mobile applications. It is able to operate over the -40°C to +105°C temperature range. The product possesses a latch-up current in the order of 25 mA minimum.

The MAX313LCUE+T’s operating voltage range can range from 2.7V to 6V dependending on the application. It uses 5V or 6V logic inputs, while its power dissipation ranges from 5mW to 6mW. Its output voltages can range up to 5V. Furthermore, its output current can range up to 0.5mA per bit and its enable time is in the order of 10µs.

In terms of working principle, the MAX313LCUE+T is divided into two cores. The first core is the multiplexer/demultiplexer core, which provides selection and routing between the channels. This core contains logic circuitry that enables selection between different channels, and a bus-type configuration with a common ground and power rail for configurations. The other core is the analog switch core which comprises 8 independent switches and provides on-off control over these switches. This switch is connected in parallel to each of the multiplexer/demultiplexer channels, and can be actuated by an enable signal.

In conclusion, the MAX313LCUE+T is a reliable, cost effective and versatile purpose CMOS multiplexer and analog switch, which is suitable for a wide range of applications including industrial control, remote monitoring, instrumentation, motor control and computer and communications. By having both the multiplexer/demultiplexer core and the independent analog switch core, the MAX313LCUE+T interface offers improved switching, low power dissipation, wide operating temperature range, low leakage current and high on-state conduction.
