Part Details:

74LCX162244 Low voltage CMOS 16-bit bus buffer (3-state) with 5V tolerant inputs and outputs Features 5V tolerant inputs and outputs High speed: ­ tPD = 4.4ns (Max) at VCC = 3V Power down protection on inputs and outputs Symmetrical output impedance: TSSOP48 ­ |IOH| = IOL = 12mA (Min) at VCC = 3V PCI bus levels guaranteed at 12mA Balanced propagation delays: Description ­ tPLH tPHL The 74LCX162244 is a low voltage CMOS 16 bit 26 serie resistor in outputs bus buffer (non-inverted) fabricated with sub- Operating voltage range: micron silicon gate and double-layer metal wiring ­ V C2MOS technology. It is ideal for low power and CC (Opr) = 2.0V to 3.6V high speed 3.3V applications; it can be interfaced Pin and function compatible with to 5V signal environment for both inputs and 74 series 162244 outputs. Latch-up performance exceeds 500mA (JESD 17) Any nG output control governs four bus buffers. Output Enable input (nG) tied together gives full ESD performance: 16-bit operation. ­ HBM > 2000V (MIL STD 883 method 3015); MM > 200V 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. 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.
