    i am struggling in problem while interfacing lpc2148 and peripherals require 5v supply. when i control the circuit i used transistor to control but for reading and writing logic at Pins it difficult.
    So if any IC to convert logic level between 3.3V to v and viceversa

    Google "logic level converter".

    Look for parts that have a Vcc range of 1.65V to 5.5V, TTL thresholds (0.8V, 2.0V), and 5V tolerant inputs.
