SP3232EEN

UMW R SP3232 3.0V TO 5.5V LOW POWER MULTICHANNEL RS-232 LINE TRANSCEIVERS USING FOR 0.1 μF EXTERNAL CAPACITORS SOP-16 DESCRIPTION The UMW SP3232EEN has two receivers and two drivers, and a dual charge-pump circuit. The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3.0V to 5.5V supply. The device operates at data signaling rates up to 250kbit/s and a maximum of 35V/μs driver output slew rate. FEATURES * Exceeds ±8KV ESD Protection(HBM) for RS-232 I/O Pins * Meets the Requirements of TIA/EIA-232-F and ITU V.28 Standards * Operates With 3.0V to 5.5V VCC Supply * Operates Up To 250kbit/s Data Rate * Two Drivers and Two Receivers * External Capacitors 4×0.1μF * Accepts 5.0V Logic Input With 3.3V Supply www.umw-ic.com 1 友台半导体有限公司 UMW R SP3232 PIN CONFIGURATION U MW SP3232 PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 www.umw-ic.com PIN NAME C1+ V+ C1C2+ C2VDOUT2 RIN2 ROUT2 DIN2 DIN1 ROUT1 RIN1 DOUT1 GND VCC DESCRIPTION Positive Terminal of Voltage-Doubler Charge-Pump Capacitor +5.5V Generated by the Charge Pump Negative Terminal of Voltage-Doubler Charge-Pump Capacitor Positive Terminal of Inverting Charge-Pump Capacitor Negative Terminal of Inverting Charge-Pump Capacitor -5.5V Generated by the Charge Pump RS-232 Driver Outputs RS-232 Receiver Inputs TTL/CMOS Receiver Outputs TTL/CMOS Driver Inputs TTL/CMOS Driver Inputs TTL/CMOS Receiver Outputs RS-232 Receiver Inputs RS-232 Driver Outputs Ground +3.0V to +5.5V Supply Voltage 2 友台半导体有限公司 UMW R SP3232 BLOCK DIAGRAM DIN1 11 14 DOUT1 DIN2 10 7 DOUT2 UMW SP3232 13 RIN1 ROUT1 12 5kΩ ROUT2 9 8 RIN2 5kΩ www.umw-ic.com 3 友台半导体有限公司 UMW R SP3232 ABSOLUTE MAXIMUM RATING [Over operating free-air temperature range (unless otherwise noted)] PARAMETER SYMBOL RATINGS UNIT Supply Voltage Range VCC -0.3 ~ +6.0 V Positive Output Supply Voltage Range (Note 2) V+ -0.3 ~ +7.0 V Negative Output Supply Voltage Range (Note 2) V+0.3 ~ -7.0 V Supply Voltage Difference (Note 2) V+ - V+13 V Drivers -0.3 ~ +6.0 V Input Voltage VIN Receivers -25 ~ +25 V Drivers -13.2 ~ +13.2 V Output Voltage VOUT Receivers -0.3 ~ VCC+0.3 V Operating Virtual Junction Temperature TJ +150 °C Storage Temperature TSTG -65 ~ + 150 °C Notes: 1.
