MC74VHCT245A  
Octal Bus Transceiver  
The MC74VHCT245A is an advanced high speed CMOS octal bus  
transceiver fabricated with silicon gate CMOS technology. It achieves  
high speed operation similar to equivalent Bipolar Schottky TTL  
while maintaining CMOS low power dissipation.  
It is intended for two−way asynchronous communication between  
data buses. The direction of data transmission is determined by the  
level of the DIR input. The output enable pin (OE) can be used to  
disable the device, so that the buses are effectively isolated.  
All inputs are equipped with protection circuits against static  
discharge.

MARKING  
DIAGRAMS  
The VHCT inputs are compatible with TTL levels. This device can  
be used as a level converter for interfacing 3.3 V to 5.0 V, because it  
has full 5.0 V CMOS level output swings.  
The VHCT245A input and output (when disabled) structures  
provide protection when voltages between 0 V and 5.5 V 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.

(Note: Microdot may be in either location)  
• Do not force a signal on an I/O pin when it is an active output,  
damage may occur.  
• All floating (high impedance) input or I/O pins must be fixed by  
means of pullup or pulldown resistors or bus terminator ICs.  
ORDERING INFORMATION  
See detailed ordering and shipping information in the package  
dimensions section on page 4 of this data sheet.
