Description
The 54AC164245 is a rad-hard advanced high-
speed CMOS, Schmitt trigger 16-bit bidirectional
multi-purpose transceiver with 3-state outputs and
cold sparing.
Designed for use as an interface between a 5 V
bus and a 3.3 V bus in mixed 5 V/3.3 V supply
systems, it achieves high-speed operation while
maintaining the CMOS low-power dissipation.
All pins have cold spare buffers to change them to
high impedance when VDD is tied to ground.
This IC is intended for two-way asynchronous
communication between the data buses and the
direction of the data transmission is determined
by the nDIR inputs.
The A port interfaces with the 3.3 V bus but can
also operate at 2.3 V. The B port operates with the
5 V bus.
Note:
Contact your ST sales office for information on the specific conditions for products in die form.

The upper metallic lid is not electrically connected to
any pins, nor to the IC die inside the package
