The 74LVX3245 is a new product in the 74LVX series, which has low power consumption and high speed. It is an interface device for 5V bus and 3.3V bus in a 5V/3.3V mixed power supply system.
The 74LVX3245 is a dual supply low voltage CMOS octal bus transceiver fabricated with sub-micron silicon gate and double-layer metal wiring CMOS technology. It is designed for use as an interface between a 5V bus and a 3.3V bus in mixed 5V/3.3V supply systems, achieving high speed operation while maintaining low power dissipation. The device allows two-way asynchronous communication between data buses, with the direction of data transmission determined by the DIR input.
