DESCRIPTION
The 74VCXH162245 is a low voltage CMOS 16
BIT BUS TRANSCEIVER (3-STATE) fabricated
with sub-micron silicon gate and five-layer metal
wiring C2MOS technology. It is ideal for low power
and very high speed 2.3 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 can be used to disable
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-
plications. Bus hold on data inputs is provided in
order to eliminate the need for external pull-up or
pull-down resistor.
