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.


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 data buses and the direction of data transmission is determined by the nDIR inputs.
