Low Voltage 16-Bit Dual Supply Translating Transceiver
with 3-STATE Outputs
General Description
Features
The VCX164245 is a dual supply, 16-bit translating trans- s Bidirectional interface between busses ranging from
ceiver that is designed for 2 way asynchronous communi-
1.65V to 3.6V
cation 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 2.3 to
3.6V and VCCA, which is the lower potential rail operating at

for translation from 1.8V to 2.5V busses to busses at a
higher potential, up to 3.3V.

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

value of the resistor is determined by the current sourcing capability of the
driver.
Advanced CMOS technology to achieve high speed opera-
tion while maintaining low CMOS power dissipation.
