Maxim MAX25014ATG/V+T

DC DC 控制器2.5V36V150mA

Overview

The MAX250ESD+TG071 and MAX251 chip set form the heart of a complete, electronically isolated, RS-232 dual transmitter/receiver. By combining many functions on two chips, the cost and complexity required for an isolated digital interface is greatly reduced. Four low cost optocouplers, four capacitors, a diode and a small pot-core type transformer are all that are required to complete a 19.2k baud transceiver. Faster data rates are possible by using high speed optocouplers. In addition to the driving and receiving circuitry for the optocouplers, the chip set includes a push-pull transformer driver to supply power to the interface's isolated side. Other convenient features include single +5V operation, a low power shutdown mode, and output enable control for three-state operation. The MAX250ESD+TG071 and MAX251 are supplied in 14 lead DIP, 14 lead small outline and 20 leadless chip carrier packages. The MAX252 has all the required components for RS-232 communication in a single package.
