The TC74ACT257 is an advanced high speed CMOS
It achieve the high speed operation similar to equivalent
This device may be used as a level converter for interfacing
Each is composed of four independent 2-channel multiplexers
If OE is set low, the outputs are held in a high-impedance
Conversely, when SELECT is high, “B” data inputs are
All inputs are equipped with protection circuits against static
