OPERATING VOLTAGERANGE:  
VCC (OPR)= 2V to 5.5V  
This device is designed to be used with 3 state  
memory address drivers, etc.  
Power down protection is provided on all inputs  
and 0 to 7V can be accepted on inputs with no  
regard to the supply voltage. This device can be  
used to interface5V to 3V.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
PIN AND FUNCTION COMPATIBLEWITH  
74 SERIES240  
IMPROVED LATCH-UP IMMUNITY  
LOWNOISE:VOLP = 0.9V(Max.)  
DESCRIPTION  
The 74VHC240 is an advanced high-speed  
CMOS OCTAL BUS BUFFER (3-STATE)  
fabricated with sub-micron silicon gate and  
double-layermetal wiring C2MOS technology.  
G output enable governs four BUS BUFFERs.
