The TC74AC257 and TC74AC258 are advanced high speed  
CMOS MULTIPLEXERs fabricated with silicon gate and  
double-layer metal wiring C2MOS technology.  
They achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
Each is composed of four independent 2-channel multiplexers  
with common SELECT and OUTPUT ENABLE ( OE ).  
The TC74AC257 is a non-inverting multiplexer, while the  
TC74AC258 is an inverting.  
If OE is set low, the outputs are held in a high-impedance  
state. When SELECT is set low, “A” data inputs are enabled.  
Conversely, when SELECT is high, “B” data inputs are  
enabled.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
