Octal Buffer/Line Driver with 3-STATE Outputs  
Features  
General Description  
High Speed: t = 5.9ns (Typ.) at V = 5V  
The VHCT244A is an advanced high speed CMOS octal  
bus transceiver fabricated with silicon gate CMOS tech-  
nology. It achieves high speed operation similar to equiv-  
alent Bipolar Schottky TTL while maintaining the CMOS  
low power dissipation. The VHCT244A is a non-  
inverting 3-STATE buffer having two active-LOW output  
enables. This device is designed to be used as 3-STATE  
memory address drivers, clock drivers, and bus oriented  
transmitter/receivers.  
PD  
CC  
Power down protection is provided on inputs and  
outputs  
Low power dissipation: I = 4µA (Max.) @ T = 25°C  
CC  
A
Pin and function compatible with 74HCT244  
Protection circuits ensure that 0V to 7V can be applied to  
(1)  
the input and output pins without regard to the supply  
voltage. These circuits prevent device destruction due to  
mismatched supply and input/output voltages. This  
device can be used to interface 5V to 3V systems and  
two supply systems such as battery back up.  
Note:
