G control output governs four BUS BUFFERs.  
This device is desibned to be used with 3 state  
memory address drivers, etc.  
VCC (OPR) = 4.5V to 5.5V  
PIN AND FUNCTION COMPATIBLE WITH  
74 SERIES 240  
IMPROVED LATCH-UP IMMUNITY  
The device is designed to interface directly High  
Speed CMOS systems with TTL, NMOS and  
CMOS output voltage levels.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
DESCRIPTION  
The ACT240 is an advanced CMOS OCTAL BUS  
BUFFER (3-STATE) fabricated with sub-micron  
silicon gate and double-layer metal wiring C2MOS  
technology. It is ideal for low power applications  
mantaining high speed operation similar to  
equivalentBipolar Schottky TTL.
