The SN74LVT2952DW is an integrated circuit component that belongs to the SN74LVT family of bus transceivers. It is a dual 4-bit bidirectional transceiver designed to work at low-voltage levels, making it compatible with both 3.3V and 5V systems. This IC is commonly used in applications where two separate data buses need to communicate bidirectionally.
An essential feature of the SN74LVT2952DW is its direction control input (DIR) that allows the user to control the data flow direction between the two buses. When DIR is set low, data from bus A will be transmitted to bus B. Conversely, setting DIR high will transfer data from bus B to bus A. This flexibility in data direction enables efficient communication between different components and systems.
The SN74LVT2952DW also incorporates a voltage translation feature to ensure seamless data transfer between systems with different voltage requirements. This is achieved by incorporating a dual-supply voltage level translation circuitry, allowing the IC to operate at a VCCA voltage level (ranging from 2.7V to 3.6V) while supporting a VCCB voltage level (ranging from 2.7V to 5.5V). The voltage translation capability makes the SN74LVT2952DW suitable for integrating with various microcontrollers, logic devices, and other ICs operating at different voltage levels
