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
VCCA, which is a higher potential rail operating at 2.3V to
3.6V and VCCB, which is the lower potential rail operating at
1.65V to 2.7V. (VCCB must be less than or equal to VCCA
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/Rn, OEn) are supplied
by VCCB.
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.
Features
s Bidirectional interface between busses ranging from
1.65V to 3.6V
s Supports Live Insertion and Withdrawal (Note 1)
s Uses patented Quiet Series noise/EMI reduction
circuitry
s Functionally compatible with 74 series 16245
s Latchup conforms to JEDEC JED78
s ESD performance:
Human Body Model >2000V
Machine model >200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA) (Preliminary)
Note 1: To ensure the high impedance state during power up or power
down, OEn should be tied to VCCB through a pull up resistor. The minimum
value of the resistor is determined by the current sourcing capability of the
driver.
