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 V
at 2.3V to 3.6V and V
rail operating at 1.65V to 2.7V. (V
or equal to V
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

The 74VCX163245 is suitable for mixed voltage applica-
