74VHC240  
Octal Buffer/Line Driver with 3-STATE Outputs  
General Description  
Features  
The VHC240 is an advanced high speed CMOS octal bus  
buffer fabricated with silicon gate CMOS technology. It  
achieves high speed operation similar to equivalent Bipolar  
Schottky TTL while maintaining the CMOS low power dissi-  
pation. The VHC240 is an inverting 3-STATE buffer having  
two active-LOW output enables. This device is designed to  
drive buslines or buffer memory address registers.  
High Speed: tPD 3.6ns (typ) at TA 25 C  
Low power dissipation: ICC  
4 A (max) @ TA 25 C  
High noise immunity: VNIH VNIL 28% VCC (min)  
Power down protection is provided on all inputs  
Low noise: VOLP 0.9V (max)  
Pin and function compatible with 74HC240  
An input protection circuit ensures that 0V to 7V can be  
applied to the input pins without regard to the supply volt-  
age. This device can be used to interface 5V to 3V systems  
and two supply systems such as battery backup. This cir-  
cuit prevents device destruction due to mismatched supply  
and input voltages.
