DESCRIPTION/ORDERING INFORMATION
The SN74LVCE161284 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 SN74LVCE161284 has one receiver dedicated to the HOST LOGIC line and a driver to drive
the PERI LOGIC line.
