  • 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 to be used 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 operations while the CMOS low-power dissipation is kept.
    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 the data transmission is determined by the nDIR inputs.
    The A port interfaces with the 3.3 V bus can also operate at 2.3 V. The B port operates with the 5 V bus.
    The 54AC164245 is packaged in hermetic ceramic Flat 48-lead screened as per MIL-PRF-38535 to comply with the needs of space applications. It is available with the upper metallic lid either floating or internally connected to ground.

    Key Features

    • Fully compatible with the 54ACS164245
    • Dual supply bidirectional level shifter
    • Extended voltage range from 2.3 V to 5.5 V
    • Separated enable pin for 3-state output
    • Schmidt-triggered I/Os: 100 mV hysteresis
    • Internal 26 Ω limiting resistor on each I/O
    • High speed: Tpd = 8 ns maximum
    • Fail safe
    • Cold spare
    • Hermetic package
    • 100 krad (Si) at any Mil1019 dose rate
    • SEL immune to 110 MeV.cm2/mg LET ions
    • RHA QML-V qualified
    • SMD: 5962R98580
