74ALVC163245
Low Voltage 16-Bit Dual Supply Translating Transceiver
with 3-STATE Outputs
General Description
The ALVC163245 is a dual supply, 16-bit translating trans-
ceiver that is designed for 2 way asynchronous communi-
cation between busses at different supply voltages by
providing true signal translation. The supply rails consist of
V
CCA
, which is a higher potential rail operating at 2.3V to
3.6V and V
CCB
, which is the lower potential rail operating at
1.65V to 2.7V. (V
CCB
must be less than or equal to V
CCA
for proper device operation). This dual supply design
allows for translation from 1.8V to 2.5V busses to busses at
a higher potential, up to 3.3V.
The Transmit/Receive (T/R) input determines the direction
of data flow. Transmit (active-HIGH) enables data from
A Ports to B Ports; Receive (active-LOW) enables data
from B Ports to A Ports. The Output Enable (OE) input,
when HIGH, disables both A and B Ports by placing them
in a High-Z condition. The A Port interfaces with the higher
voltage bus (2.7V to 3.3V); The B Port interfaces with the
lower voltage bus (1.8V to 2.5V). Also the ALVC163245 is
designed so that the control pins (T/R
n
, OE
n
) are supplied
by V
CCB
.
The 74ALVC163245 is suitable for mixed voltage applica-
tions such as notebook computers using a 1.8V CPU and
3.3V peripheral components. It is fabricated with an
Advanced CMOS technology to achieve high speed opera-
tion while maintaining low CMOS power dissipation.

Note 1:
To ensure the high impedance state during power up or power
down, OE
n
should be tied to V
CCB
through a pull up resistor. The minimum
value of the resistor is determined by the current sourcing capability of the
driver.
