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.
General Description
The VCX163245 is a dual supply, 16-bit translating
transceiver that is designed for 2 way asynchronous
communication between busses at different supply volt-
ages 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 direc-
tion 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 plac-
ing 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 VCX163245 is designed so that the control pins
(T/Rn, OEn) are supplied by VCCB.
The 74VCX163245 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 oper-
ation while maintaining low CMOS power dissipation.
