PI5C3245LEX is a 20-channel, 3.3V CML level translator optimized to translate a differential Low Voltage Transceiver Interface Signaling (LVTTL) to Common Mode Logic (CML) levels. This device is ideal for use in providing level translation buffers between the LVTTL buses and high-speed communication interface protocols such as Multi-Mode Fiber Optics (MMFO) and USB. It is also suitable for driving high speed Analog-to-Digital Converters (ADC) and Digital-to-Analog Converters (DAC). It is ideal for applications where low power and small size are required, such as memory and digital imaging.

The PI5C3245LEX has two independent LVTTL channels, each with differences of 50, 100, 150, and 200 mV from common mode voltage, which support full swing (2.6V to 3.3V) and half swing (1.8V to 2.6V) data buses. The device is controlled by two inputs, which can be used to select the channel and logic direction. The logic inputs and outputs are TTL compatible. The logic output swing is approximately 0.4V for a logic low and 2.6V for a logic high.

The PI5C3245LEX belongs to the class of Logic - Signal Switches, Multiplexers and Decoders. A Multiplexer (MUX) is a device that is used to switch between multiple input signals and connect the chosen signal to an output. The MUX switches the signal using two select lines, and the output is controlled by an enable line. A Decoder is a circuit that is used to decode an input signal, typically known as an address, into a set of individual outputs. A Switch (or Switching Device) is a device that is used to control the flow of signals between two or more points in a circuit. The switch can be used to control the on-off state of a signal, or to switch between multiple signals.

The PI5C3245LEX works on the principle of signal switching and decoding. The device is controlled by two inputs, which are used to select the LVTTL channel and the logic direction. The logic inputs and outputs are TTL compatible and are used to control the logic output of the selected signal. The device can also be used to switch between multiple signals, by using the two select lines, as well as to decode an input signal.

The PI5C3245LEX is an ideal solution for providing level translation between LVTTL buses and high-speed communication protocols, as well as for driving high speed ADCs and DACs. This device is also well suited for low power applications, such as memory and digital imaging, due to its small size and low power consumption.
