DESCRIPTION
The 74ACT245 is an advanced high-speed CMOS
OCTAL
BUS
TRANSCEIVER
fabricated with sub-micron silicon gate and
double-layer metal wiring C
2
MOS tecnology.
This IC is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
DIR input. The enable input G can be used to
disable the device so that the buses are effectively
isolated.
(3-STATE)
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
IT IS PROHIBITED TO APPLY A SIGNAL TO A
TERMINAL WHEN IT IS IN OUTPUT MODE AND
WHEN A BUS THERMINAL IS FLOATING (HIGH
IMPEDANCE STATE) IT IS REQUIRED TO FIX
THE INPUT LEVEL BY MEANS OF EXTERNAL
PULL DOWN OR PULL UP RESISTOR.
