te PDESCRIPTION
leThe 74ACT245 is an advanced high-speed CMOS
oOCTAL BUS TRANSCEIVER (3-STATE)
sfabricated with sub-micron silicon gate and
bdouble-layer metal wiring C2MOS tecnology.
OThis IC is intended for two-way asynchronous
-communication between data buses and the
)direction of data transmission is determined by
t(sDIR input. The enable input G can be used to
cdisable the device so that the buses are effectively
uisolated.

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.
