TC74ACT257P/F/FN  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74ACT257P,TC74ACT257F,TC74ACT257FN  
2-Channel Multiplexer (3-state)  
Note: xxxFN (JEDEC SOP) is not available in  
Japan.  
The TC74ACT257 is an advanced high speed CMOS  
MULTIPLEXER fabricated with silicon gate and double-layer  
metal wiring C2MOS technology.  
TC74ACT257P  
It achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
This device may be used as a level converter for interfacing  
TTL or NMOS to High Speed CMOS. The inputs are compatible  
with TTL or NMOS and CMOS output voltage levels.  
Each is composed of four independent 2-channel multiplexers  
with common SELECT and OUTPUT ENABLE ( OE ).  
TC74ACT257F  
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.
