| 54VCXH162244 Low voltage CMOS 16-bit bus buffer (3-state inverter) with 3.6V tolerant inputs and outputs Features 1.65 to 3.6V inputs and outputs High speed: - tPD = 3.4ns at VCC = 3.0 to 3.6V - tPD = 3.8ns at VCC = 2.3 to 2.7V Power down protection on inputs and outputs Symmetrical output impedance: - |IOH| = IOL = 12mA (Min) at VCC = 3.0V - |IOH| = IOL = 8mA (Min) at VCC = 2.3V 26 serie resistors in outputs Operating voltage range: - VCC(Opr) = 1.65V to 3.6V Pin and function compatible with 54 SERIES H162244 Bus hold provided on data inputs Cold spare function Latch-up performance exceeds 300mA (JESD 17) ESD performance: - HBM > 2000V (MIL STD 883 method 3015); MM > 200V 300KRad Mil1019.6 Condition A, (RHA QML qualification extension undergone) No SEL, no SEU under 72 Mev/cm2/mg LET heavy ions irradiation QML qualified product SMD 5962-05210 Flat-48 Description The 54VCXH162244 is a low voltage CMOS 16 bit bus buffer (non inverted) fabricated with submicron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for low power and very high speed 1.65 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. Any nG output control governs four BUS buffers. Output Enable input (nG) tied together gives full 16-bit operation. When nG is low, the outputs are on. When nG is HIGH, the output are in high impedance state. This device is designed to be used with 3 state memory address drivers, etc. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. The device circuits is including 26 series resistance in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
