74VHCT240A  
Octal Buffer/Line Driver with 3-STATE Outputs  
due to mismatched supply and input/output voltages. This  
General Description  
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  
The VHCT240A 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 VHCT240A is an inverting 3-STATE  
buffer having two active-LOW output enables. This device  
is designed to be used as 3-STATE memory address driv-  
ers, clock drivers, and bus oriented transmitter/receivers.  
Features  
■ High Speed:  
tPD = 5.6 ns (typ) at VCC = 5V  
■ Power down protection is provided on inputs and  
outputs  
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  
■ Low power dissipation:  
ICC = 4 µA (max) @ TA = 25°C  
■ Pin and function compatible with 74HCT240
