25V-Powered, True RS-232 Dual Transceiver
_______________General Description
The MAX218 RS-232 transceiver is intended for batterypowered EIA/TIA-232E and V.
28/V.
24 communications interfaces that need two drivers and two receivers with minimum power consumption.
It provides a wide +1.
8V to +4.
25V operating voltage range while maintaining true RS-232 and EIA/TIA-562 voltage levels.
The MAX218 runs from two alkaline, NiCd, or NiMH cells without any form of voltage
regulator.
A shutdown mode reduces current consumption to 1µA, extending battery life in portable systems.
While shut down, all receivers can remain active or can be disabled under logic control, permi...
