Pin Assignment

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

High speed: t

Low power dissipation: I

Compatible with TTL outputs: V

Symmetrical output impedance: |I

Balanced propagation delays: t
