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 twoway 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.
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
hel p prevent devi c e des t r uct i o n caus e d by suppl y
voltageinput/output voltage mismatch, battery backup, hot insertion,
etc.

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.
