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. 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.
