  • 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 to be used 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 operations 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 a two-way asynchronous communication between data buses. The direction of data transmission is determined by the nDIR inputs.

    Key Features

    • Dual supply bidirectional level shifter
    • Voltage range from 1.6 V to 3.6 V
    • Separated enable pin for 3-state output
    • Internal 26 Ω limiting resistor on each I/O
    • Bus hold
    • Fail safe
    • Cold spare
    • Hermetic package
    • 300 k/rad (Si) at any Mil1019 dose rate
    • SEL immune to 110 MeV.cm2/mg LET ions
    • QML-V qualification on-going
