Description
The SN74AXC4T774RSVR is a high-performance, low-voltage, bidirectional voltage level translator from Texas Instruments. It is designed to seamlessly translate signals between different voltage nodes, supporting a flexible range from 0.65 V to 3.6 V on both VCCA and VCCB sides. This makes it suitable for interfacing components with different voltage levels in mixed-signal systems. The device features four independent channels, allowing for simultaneous translation of signals in either direction, accommodating various data rates and bit widths.
The SN74AXC4T774RSVR is optimized for low power consumption and includes an output-enable (OE) input to place the outputs in a high-impedance state, further reducing power usage. It boasts a high-speed operation with a maximum data rate of 500 Mbps at 1.8 V to 3.3 V translation, making it ideal for applications requiring fast signal processing. The compact package and robust ESD protection enhance its integration and reliability in portable and space-constrained designs. Typical applications include mobile devices, computing, and industrial systems requiring precise and efficient voltage level translation.
