MAX3232
SINGLE SUPPLY RS-232 STANDARD TRANSCEIVER
DESCRIPTION
PIN CONFIGURATION
MAX3232 is compatible with RS-232 standard, have dual
transceiver. Each receiver converts TIA/EIA-232-E levels
into TTL/CMOS levels. Each driver converts TTL/CMOS
levels into TIA/EIA-232-E levels. The MAX3232 is characterized for operation from -40°C to +85°C for all packages.
D or N Package
MAX3232 is purposed for application in high-performance
information processing systems and control devices of wide
application.
