54VCXH162244 Low voltage CMOS 16-bit bus buffer (3-state non inverter) with 3.6 V tolerant inputs and outputs Features 1.65 to 3.6 V inputs and outputs High speed: t = 3.4 ns at V = 3.0 to 3.6 V PD CC t = 3.8 ns at V = 2.3 to 2.7 V PD CC Power down protection on inputs and outputs Symmetrical output impedance: Flat-48 I = I = 12 mA (Min.) at V = 3.0 V OH OL CC I = I = 8 mA (Min.) at V = 2.3 V OH OL CC The upper metallic lid is not electrically connected to any 26 serie resistors in outputs pins, nor to the IC die inside the package. Operating voltage range: V (Opr) = 1.65 V to 3.6 V CC Description Pin and function compatible with 54 series H162244 The 54VCXH162244 is a low voltage CMOS 16 bit bus buffer (non inverted) fabricated with sub- Bus hold provided on data inputs micron silicon gate and five-layer metal wiring Cold spare function CMOS technology. It is ideal for low power and Latch-up performance exceeds very high speed 1.65 to 3.6 V applications it can 300 mA (JESD 17) be interfaced to 3.6 V signal environment for both inputs and outputs. Any nG output control ESD performance: governs four BUS buffers. Output enable input HBM > 2000 V (nG) tied together gives full 16-bit operation. (Mil Std 883 Method 3015) MM > 200 V When nG is low, the outputs are on. When nG is 300 krad Mil1019.6 condition A, (RHA QML high, the output are in high impedance state. This qualification extension undergone) device is designed to be used with 3 state memory address drivers, etc. Bus hold on data No SEL, no SEU and no SET under 110 inputs is provided in order to eliminate the need Mev/cm2/mg LET heavy ions irradiation for external pull-up or pull-down resistor. The QML qualified product device circuits is including 26 series resistance SMD 5962-05210 in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs 100 mV typical input hysteresis and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.
