74VHCT240AT  
G output enable governs four BUS BUFFERs.  
This device is designed to be used with 3 state  
memory address drivers, etc.  
OPERATING VOLTAGERANGE:  
VCC (OPR)= 4.5V to 5.5V  
PIN AND FUNCTION COMPATIBLEWITH  
74 SERIES240  
Power down protection is provided on all inputs  
and outputs and 0 to 7V can be accepted on  
inputs with no regard to the supply voltage. This  
device can be used to interface 5V to 3V.  
IMPROVED LATCH-UP IMMUNITY  
LOWNOISE:VOLP = 0.9V(Max.)  
DESCRIPTION  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
The 74VHCT240A is an advanced high-speed  
CMOS OCTAL BUS BUFFER (3-STATE)  
fabricated with sub-micron silicon gate and  
double-layermetal wiring C2MOS technology.
