Part Description: OW VOLTAGE CMOS 16-BIT BUFFER (3-STATE) WITH 5V TOLERANT INPUTS AND OUTPUTS


Part Details:

74LCX16244 Low voltage CMOS 16-bit bus buffer (3-state) with 5V tolerant inputs and outputs Features 5V tolerant inputs and outputs High speed: ­ tPD = 4.5ns (Max) at VCC = 3V Power down protection on inputs and outputs Symmetrical output impedance: TSSOP48 ­ |IOH| = IOL = 24mA (Min) at VCC = 3V PCI bus levels guaranteed at 24mA Balanced propagation delays: Description ­ tPLH tPHL The 74LCX16244 is a low voltage CMOS 16 bit Operating voltage range: bus buffer (non-inverted) fabricated with sub- ­ V micron silicon gate and double-layer metal wiring CC (Opr) = 2.0V to 3.6V C2MOS technology. It is ideal for low power and Pin and function compatible with high speed 3.3V applications; it can be interfaced 74 series 16244 to 5V signal environment for both inputs and Latch-up performance exceeds outputs. 500mA (JESD 17) Any nG output control governs four BUS ESD performance: BUFFERS. Output Enable input (nG) tied together ­ HBM > 2000V gives full 16-bit operation. (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. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
