The SN75C3222PWR is an integrated level translator designed to interface between 1.8V to 3.6V, as well as between 1.8V and 5V powered systems such as microcontrollers, digital storage devices, and other digital functions found in embedded designs. It is classified as a 3-state, low-voltage Schottky TTL, which makes it an interface driver, receiver, or transceiver that has been combined into one device. The SN75C3222PWR is designed to provide flexibility and the ability to bridge a variety of voltage levels while also providing galvanic isolation between the input and output circuits. It is commonly used to interface between logic and other digital devices as well as to bridge different ground circuits.
The SN75C3222PWR has certain features which make it suitable for a variety of applications, such as automotive and industrial control, low-power embedded systems, and other applications that require low power consumption and minimal EMI/RFI. It is available in the SOT-23 and TSSOP-8 packages which allow for use in space-restricted designs. The SN75C3222PWR also has a low operating voltage which allows it to be used in battery-operated systems, as well as to help alleviate noise issues that arise when using a low-voltage supply. In addition, the device has a stand-by current of less than 125pA and a sleep current of less than 5uA, making it suitable for low-power applications.
The SN75C3222PWR is a single-channel ATEC device which allows it to be used as either an interface driver, receiver, or transceiver. It functions by providing bidirectional level shifting between 1.8V and 3.6V or between 1.8V and 5.0V. It is designed to be used between 3.3V to 5V microcontrollers, as well as between a 1.8V and 3.3V powered microcontroller. When used as an interface driver, it will allow 3.3V logic to drive 5V logic, or 5V logic to drive 1.8V logic. When used as a receiver, it will allow 1.8V logic to be driven by 5V logic, or 3.3V logic to be driven by 5V logic. When used as a transceiver, it will allow signals to be passed between different voltage levels without conversion.
The SN75C3222PWR also functions as a buffer and provides a low-impedance output which isolates the load from the input, allowing for good noise immunity. It is designed to minimize power consumption and provide a wide operating voltage range of 1.6V – 5.5V. In addition, it I has a low operating current of 113µA (typical) and an input threshold voltage range of 0.75V – 5.5V, making it suitable for use in low-power applications. Furthermore, it has a low output current capability (1.5mA or 2.5mA) which helps to alleviate any current demand problems on the Load.
The SN75C3222PWR is designed to provide flexibility and the ability to bridge a variety of voltage levels while also providing galvanic isolation between the input and output circuits. It is commonly used to interface between logic and other digital devices as well as to bridge different ground circuits. Its primary applications include interfacing microcontrollers, digital storage devices, low-power embedded systems, and other applications that require minimal EMI/RFI and low power consumption. Thus, the SN75C3222PWR is the perfect device for bridging between the digital and analog domains and providing galvanic isolation in embedded systems.
