TLC27L2CDR

The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. Brand : Texas Instruments DATASHEET

The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step-down switching regualtor(buck converter). All circuits of this series are capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V,12V, 15V, and an adjustable output version.

The LM29300 are high current, high accuracy, low-dropout voltage regulators. Using process with a PNP pass element, these requlators feature 350mV (full load) dropout voltages and very low ground current. Brand : HTC DATASHEET

The SN65176B and SN75176B differential bus transceivers are designed for bidirectional data communication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27. Brand : Texas Instruments DATASHEET
