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 2 way asynchronous communi-
cation between busses at different supply voltages by
providing true signal translation. The supply rails consist of
V
CCB
, which is the higher potential rail operating at 2.3 to
3.6V and V
CCA
, which is the lower potential rail operating at
1.65 to 2.7V. (V
CCA
must be less than or equal to V
CCB
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 P Ports by placing them in a
High-Z condition. The A Port interfaces with the lower volt-
age bus (1.8
2.5V); The B Port interfaces with the higher
voltage bus (2.7
3.3V). Also the VCX164245 is designed
so that the control pins (T/R
n
, OE
n
) are supplied by V
CCB
.
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.

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.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
