74VCX164245
Low Voltage 16-Bit Dual Supply Translating Transceiver
with 3-STATE Outputs
General Description
The VCX164245 is a dual supply, 16-bit translating trans-
ceiver that is designed for two way asynchronous commu-
nication between busses at different supply voltages by
providing true signal translation. The supply rails consist of
VCCB, which is the higher potential rail operating at 2.3V to
3.6V and VCCA, which is the lower potential rail operating at
1.65V to 2.7V. (VCCA must be less than or equal to VCCB
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 lower volt-
age bus (1.8V
2.5V). The B Port interfaces with the
higher voltage bus (2.7V
3.3V). Also the VCX164245 is
designed so that the control pins (T/Rn, OEn) are supplied
by VCCB.
The 74VCX164245 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 Static Drive (IOH/IOL)
r24 mA @ 3.0V VCC
r18 mA @ 2.3V VCC
r6 mA @ 1.65V VCC
s Functionally compatible with 74 series 16245
s Latchup performance exceeds 300 mA

Human Body Model
!2000V
Machine model
!200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
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.
Ordering Code:
Note 2: Ordering Code “G” indicates Trays.
Note 3: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
