74VHCT244A  
Octal Buffer/Line Driver with 3-STATE Outputs  
General Description  
Features  
The VHCT244A is an advanced high speed CMOS octal  
bus transceiver fabricated with silicon gate CMOS technol-  
ogy. It achieves high speed operation similar to equivalent  
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.  
High Speed: tPD 5.9 ns (typ) at VCC 5V  
Power down protection is provided on inputs and  
outputs  
Low power dissipation: ICC  
4 A (max) @ TA 25 C  
Pin and function compatible with 74HCT244  
Protection circuits ensure that 0V to 7V can be applied to  
the input and output (Note 1) 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 1: Outputs in OFF-State
