DESCRIPTION
The ACT245 is an advanced CMOS OCTAL BUS
TRANSCEIVER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology. It is ideal for low
power applications mantaining high speed
operation similar to equivalent Bipolar Schottky
TTL.
This IC is intended for two-way asynchronous
communication between data buses and the
PIN CONNECTION AND IEC LOGIC SYMBOLS

direction of data trasmission is determined by
DIR input. The enable input G can be used to
disable the device so that the buses are
effectively isolated.
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 REQUESTED
TO FIX THE INPUT LEVEL BY MEANS OF
EXTERNAL PULL DOWN OR PULL UP
RESISTOR.
