SN75C3221EPWR

15kV ESD Protected 3V to 5.5V Single-Channel RS-232 Transceiver manufactured by Texas Instruments. This high-speed serial communication interface integrated circuit features an integrated low-dropout transmitter and a receiver loop inside a 16-pin thin shrink small outline package (TSSOP-16). It functions by operating on a single 3.3V or 5V power line, utilizing dual on-chip charge pumps to generate standard RS-232 bipolar voltage swings while providing robust 15,000-Volt ESD protectionon all serial pins to block destructive static arc damage during live cable plug-ins. It is standard infrastructure for data terminal interfaces, industrial programmable logic controllers (PLCs), commercial POS cash registers, and network server configuration serial lines.
