PI3C3245LE is a handy, high-speed Level Shifter/Translator that shifts/translates low voltage to high voltage and vice versa. Its flexible operating range and efficient power output make it a valuable asset in a variety of applications. Its ability to accurately level-shift resolutions of up to 24-bits per frame makes it an ideal choice for telecom, consumer and industrial applications. The PI3C3245LE Level Shifter/Translator is an excellent choice for applications including mobile devices, digital audio, imaging and server/storage.

The PI3C3245LE can be classified as a Logic - Signal Switches, Multiplexers, Decoders. The device performs three primary functions, SN74AVC4T245 Logic-Level Translator, SN74AVC4T245 Circuit Enable (CE) Logic Input and SN74AVC4T245 Circuit Select (CS) Logic Input. The SN74AVC4T245 allows easy logic-level translation between low voltage and high voltage logic with full support for common Vcc and Vcc Supplies. The Logic Input CE controls the power and operation of the Level Shifter/Translator while the Logic Input CS enables the Logic Input CE to toggle the Level Shifter/Translator from powered on to powered off state. Both, Logic Input CE and Logic Input CS are active high.

The PI3C3245LE works by using its two input logic levels, VLL and VHH, to determine the output logic level of the logic channel. This logic channel is then shifted to the high voltage level using the VHH reference level. If data is sent from a low voltage device to the PI3C3245LE, it will use the VLL reference level to shift the data and then output it in the higher voltage range. Thus, the device is particularly useful when communicating between high and low voltage devices.

In the PI3C3245LE’s typical application circuit, it is necessary to have a pull-up or pull-down resistor connected to the device’s Logic Input (LE). The selection of the resistor used between the LE and ground depends on the high/low threshold used in the application. In most cases, the threshold will be either 5V or 3V. If a 5V threshold is used, a pull-up resistor of 2.2K ohms should be used. If a 3V threshold is used, a pull-down resistor of 2.2K ohms should be used. By using this resistor, a smoother transition of the logic level from high to low is achieved.

The PI3C3245LE Level Shifter/Translator can be used in a wide range of telecom, consumer, and industrial applications. On the telecom side, the device is capable of correctly accessing devices that use a 24-bit resolution. On the consumer side, the device is capable of supporting digital audio and imaging devices. On the industrial side, digital televisions, server/storage systems and alarms. can take advantage of the PI3C3245LE’s ability to accurately level-shift large resolution signals.

In summary, the PI3C3245LE Level Shifter/Translator is a versatile device that can be used in a variety of applications. The device’s ability to switch logic levels and its wide operating range make it an excellent choice for telecom, consumer and industrial applications. The need for a pull-up or pull-down resistor depends on the application and its threshold levels, but this element is generally necessary to achieve the smoothest signal transition.
