DESCRIPTION
The 74VCX162245 is a low voltage CMOS 16 BIT
BUS TRANSCEIVER (3-STATE) fabricated with
sub-micron silicon gate and five-layer metal wiring
C
2
MOS technology. It is ideal for low power and
very high speed 1.8 to 3.6V applications; it can be
interfaced to 3.6V signal environment for both
inputs and outputs.
This IC is intended for two-way asynchronous
communication between data buses; the direction
of data transmission is determined by DIR input.
The two enable inputs nG canbeusedtodisable
the device so that the buses are effectively
isolated. The device circuits is including 26Ω se-
ries resistance in the A port outputs. These resis-
tors permit to reduce line noise in high speed ap-
