description/ordering information
The SN74LVCZ161284A is designed for 3-V to
3.6-V VCC operation. This device provides
asynchronous two-way communication between
data buses. The control-function implementation
minimizes external timing requirements.

This device has eight bidirectional bits; data can flow in the A-to-B direction when the direction-control
input (DIR) is high, and in the B-to-A direction when DIR is low. This device also has five drivers that drive the
cable side and four receivers. The SN74LVCZ161284A has one receiver dedicated to the HOST LOGIC line
and a driver to drive the PERI LOGIC line.
