that the busses are effectively isolated. The 26-Ω series resistor

helps reducing output overshoot and undershoot without external

Features (Note 1)

•

The TC74VCXR2245 is a high-performance CMOS octal bus

It is also designed with overvoltage tolerant inputs and outputs up

The direction of data transmission is determined by the level of the

All inputs are equipped with protection circuits against static

Note 1: When mounting VQON package, the type of recommended flux is RA or RMA.
