PI5C3253LEX

The PI5C3253LEX is a Logic-Signal Switch, Multiplexer and Decoder IC that is manufactured by Exar Corporation who specializes in designing ICs which handle communications, analogue and digital data, power management and other integrated solutions. It is a beneficial IC, particularly in applications where there are many signals that require to be switched or multiplexed.

The PI5C3253LEX is available in a 5-pin single-in-line package and offers a wide operating voltage range from 1.5V to 5.5V and can operate over temperatures ranging from -40°C to +125°C. The input logic levels of this IC include LVCMOS, LVTTL and LVTTL with hysteresis, while the output is available in either bi-directional TTL or LVCMOS, whichever is more suitable for the system.

The PI5C3253LEX features two independent non-inverting switches, two multiplexers, one digital controlled oscillator (DCO), two high frequency decoders and two high speed voltage level translators. Each of the two independent non-inverting switches has two inputs and three selectable output pins, allowing for a wide range of switching operations. One of the multiplexers has three inputs and one output, while the other multiplexer has two inputs and one output.

The DCO is available on the PI5C3253LEX to allow for the generation of waveforms as it outputs a programmed frequency or pulse width either in continuous or single pulse modes. The two high frequency decoders provide high frequency clocks from a single clock input, while the voltage level translators can be used to transfer data signals from one voltage domain to another, while maintaining the same logical output level.

The working principle of the PI5C3253LEX is simple. When the power is applied to the IC, the internal logic detects the logic levels at the inputs and the data is then translated into the desired output logic level whether it is TTL or LVCMOS. The two multiplexers allow for selecting one of the two logic levels either individually or selecting several at a time, while the two high frequency decoders can provide high frequency clocks from a single clock input.

The PI5C3253LEX is widely used in a variety of application fields such as mobile phones, digital cameras, gaming applications and network infrastructure, among others. Furthermore, it is widely utilized for storage systems, automotive electronics and medical imaging equipment.

In summary, the PI5C3253LEX is a Logic-Signal Switch, Multiplexer and Decoder IC that provides a wide range of switching and multiplexing options. It is used in a variety of applications from mobile phones and gaming applications to automotive electronics and medical imaging equipment due to its wide operating voltage range, suitable input and output levels and various features.
