MC74LVX245
Octal Bus Transceiver
With 5 VTolerant Inputs
The MC74LVX245 is an advanced high speed CMOS octal bus
transceiver.
It is intended for twoway asynchronous communication between
data buses. The direction of data transmission is determined by the
level of the T/R 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.

Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300 mA
ESD Performance: Human Body Model > 2000 V;
Machine Model > 200 V
PbFree Packages are Available*
Application Notes
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
A parasitic diode is formed between the bus and V
CC
terminals.
Therefore, the LVX245 cannot be used to interface 5.0 V to 3.0 V
systems directly
