Data brief
The 54VCXH163245 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 3.3 V
bus and a 1.8 V bus in mixed 3.3 V / 1.8 V supply
systems, it achieves high-speed operation while
maintaining the CMOS low power dissipation.

model
All pins have cold spare buffers to change them to
high impedance when V
is tied to ground.
DD
This IC is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
the nDIR inputs.
