74VHC244  
Octal Buffer/Line Driver with 3-STATE Outputs  
General Description  
Features  
The VHC244 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 VHC244 is a non-inverting 3-STATE buffer hav-  
ing two active-LOW output enables. These devices are  
designed to be used as 3-STATE memory address drivers,  
clock drivers, and bus oriented transmitter/receivers.  
High Speed: tPD 3.9ns (typ) at VCC 5V  
High noise immunity: VNIH VNIL 28% VCC (min)  
Power down protection is provided on all inputs  
Low noise: VOLP 0.6V (typ)  
Low power dissipation: ICC  
4 A (max) @ TA 25 C  
Pin and function compatible with 74HC244  
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 back up. This cir-  
cuit prevents device destruction due to mismatched supply  
and input voltages.
