Logic - Translators, Level Shifters are digital circuits used for data transmission between components at different voltage levels. ST2349AQTR is a commonly used low-voltage level-translator, transceiver and bus-switch, designed to operate with a single-ended voltage range of 1.05 to 2.5V. It is widely used in various consumer and industrial applications.

The ST2349AQTR has six input/output (I/O) ports with iA or iB function, which can switch between single-ended or bidirectional switching. The iB port can detect the bias current of the power supply pins and control the output voltage level automatically, while the iA port must be set manually. The Vcc pin must be connected to a voltage source to provide power for the device, and the Vss pin is connected to the system ground.

The ST2349AQTR features two separate low-voltage data pins (D1, D2) for data transmission and two enable pins (DE/EN1, DE/EN2) to manually enable or disable the data pins. The D1 and D2 pins are used for single-ended and bidirectional data transmission. When DE/EN1 and DE/EN2 are high, the two data pins will transmit data. When these pins are low, the two data pins will be disabled.

The ST2349AQTR supporting data transmission rate up to 800 Mbps, offering Schmitt-trigger inputs, among other features. The device supports bidirectional data transmission, which is achieved by connecting the two enable pins in order. The ST2349AQTR provides adaptive voltage-level shifting, allowing data transmission over 1.05 to 2.5V. It can also be used to switch small signals and provide power isolation in secure systems.

The ST2349AQTR also features a high-speed, low-voltage logic level, allowing data transmission at up to 800 Mbps. The Schmitt-trigger input enables logic conversion, which prevents damage from low voltage noise. The device can also be used for bus arbitration and side-channel communication.

In summary, the ST2349AQTR is a widely used low voltage, level-translator, transceiver and bus-switch. It features two separate I/O ports, two enable pins, Schmitt-trigger inputs and adaptive voltage-leve using a supply voltage between 1.05 and 2.5V for data transmission up to 800 Mbps. It can be used for data transmission, bus arbitration, side-channel communication and power isolation in secure systems.
