  • The 54VCXHR162245 is a low voltage CMOS 16-bit bus transceiver (3-state) developed with sub-micron silicon gate and five-layer metal wiring C²MOS technology. It is ideal for low power and very high speed 1.65 to 3.6 V applications; it can be interfaced to 3.6 V signal environment for both inputs and outputs. This IC is intended for two-way asynchronous communication between data buses; the direction of data transmission is determined by DIR input. The two enable inputs nG can be used to disable the device so that the buses are effectively isolated. The device circuits include 26 Ω series resistance in the A and B port outputs. These resistors reduce the line noise in high speed applications. Bus hold on data inputs is provided in order to eliminate the need for the external pull-up or pull-down resistor. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage. All floating bus terminals during high Z state must be held HIGH or LOW.

    Key Features

    • 1.65 to 3.6 V inputs and outputs
    • High speed in both A, B outputs:

      • tPD= 4.3 ns at VCC= 2.3 to 2.7 V
    • Symmetrical impedance outputs:
      • |IOH| = IOL= 12 mA (Min.) at VCC= 3.0 V
      • |IOH| = IOL= 8 mA (Min.) at VCC= 2.3 V
    • Power down protection on inputs and outputs
    • 26 Ω serie resistors in both A and B port outputs
