The TC74LCX164245FT is a dual supply, advanced high-speed CMOS 16-bit dual supply voltage interface bus transceiver fabricated with silicon gate CMOS technology.
Designed for use as an interface between a 5-V bus and a 3.3-V or 2.5-V bus in mixed 5-V/3.3-V or 2.5-V supply systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.
It is intended for 2 way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input (OE) can be used to disable the device so that the buses are effectively isolated. The B-port interfaces with the 5-V bus, the A-port with the 3.3-V or 2.5-V bus.
All inputs of the TC74LCX164245FT are equipped with protection circuits against static discharge or transient excess voltage.
