SEMICONDUCTOR TECHNICAL DATA  
The MC74VHCT540A is an advanced high speed CMOS inverting octal  
bus buffer fabricated with silicon gate CMOS technology. It achieves high  
speed operation similar to equivalent Bipolar Schottky TTL while maintaining  
CMOS low power dissipation.  
The MC74VHCT540A features inputs and outputs on opposite sides of the  
package and two AND–ed active–low output enables. When either OE1 or  
OE2 are high, the terminal outputs are in the high impedance state.  
The VHCT inputs are compatible with TTL levels. This device can be used  
as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS  
level output swings.  
DW SUFFIX  
20–LEAD SOIC WIDE PACKAGE  
CASE 751D–05  
The VHCT540A input and output (when disabled) structures provide  
protection when voltages between 0V and 5.5V are applied, regardless of  
the supply voltage. These input and output structures help prevent device  
destruction caused by supply voltage – input/output voltage mismatch,  
battery backup, hot insertion, etc.  
DT SUFFIX  
20–LEAD TSSOP PACKAGE  
CASE 948E–02  
The internal circuit is composed of three stages, including a buffer output  
which provides high noise immunity and stable output. The inputs tolerate  
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
