MC74VHC245

Octal Bus Buffer/Line Driver

The MC74VHC245 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.

= Pb−Free Package

• 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 pull up or pull down resistors or bus terminator ICs.

(Note: Microdot may be in either location)

• A parasitic diode is formed between the bus and V terminals.

ORDERING INFORMATION

Therefore, the VHC245 cannot be used to interface 5 V to 3 V

systems directly.
