HIN232, HIN236, HIN237, HIN238, HIN239, HIN240, HIN241 Data Sheet September 26, 2008 FN3138.16 +5V Powered RS-232 Features Transmitters/Receivers Meets All RS-232E and V.28 Specifications The HIN232-HIN241 family of RS-232 transmitters/receivers Requires Only Single +5V Power Supply interface circuits meet all ElA RS-232E and V.28 specifications, - (+5V and +12V - HIN239) and are particularly suited for those applications where 12V is High Data Rate . 120kbps not available. They require a single +5V power supply (except HIN239) and feature onboard charge pump voltage converters Onboard Voltage Doubler/Inverter which generate +10V and -10V supplies from the 5V supply. Low Power Consumption The family of devices offer a wide variety of RS-232 transmitter/receiver combinations to accommodate various Low Power Shutdown Function applications (see Selection Table on page 1). Three-State TTL/CMOS Receiver Outputs The drivers feature true TTL/CMOS input compatibility, Multiple Drivers slew-rate-limited output, and 300 power-off source - 10V Output Swing for 5V lnput impedance. The receivers can handle up to 30V, and have -300 Power-Off Source Impedance a 3k to 7k input impedance. The receivers also feature - Output Current Limiting hysteresis to greatly improve noise rejection. - TTL/CMOS Compatible - 30V/s Maximum Slew Rate Multiple Receivers - 30V Input Voltage Range -3k to 7k Input Impedance - 0.5V Hysteresis to Improve Noise Rejection Pb-free Available (RoHS compliant) Applications Any System Requiring RS-232 Communication Ports - Computer - Portable, Mainframe, Laptop - Peripheral - Printers and Terminals - Instrumentation - Modems Selection Table NUMBER OF NUMBER OF LOW POWER PART POWER SUPPLY RS-232 RS-232 EXTERNAL SHUTDOWN/TTL NUMBER OF NUMBER VOLTAGE DRIVERS RECEIVERS COMPONENTS THREE-STATE LEADS HIN232 +5V 2 2 4 Capacitors No/No 16 HIN236 +5V 4 3 4 Capacitors Yes/Yes 24 HIN237 +5V 5 3 4 Capacitors No/No 24 HIN238 +5V 4 4 4 Capacitors No/No 24 HIN239 +5V and +7.5V to 13.2V 3 5 2 Capacitors No/Yes 24 HIN240 +5V 5 5 4 Capacitors Yes/Yes 44 HIN241 +5V 4 5 4 Capacitors Yes/Yes 28 CAUTION: These devices are sensitive to electrostatic discharge follow proper IC Handling Procedures. 1 1-888-INTERSIL or 1-888-468-3774 Intersil (and design) is a registered trademark of Intersil Americas Inc.

CC V+ Internally generated positive supply (+10V nominal), HIN239 requires +7.5V to +13.2V. V- Internally generated negative supply (-10V nominal). GND Ground lead. Connect to 0V. C1+ External capacitor (+ terminal) is connected to this lead. C1- External capacitor (- terminal) is connected to this lead. C2+ External capacitor (+ terminal) is connected to this lead. C2- External capacitor (- terminal) is connected to this lead. T Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400k pull-up resistor to V is connected to each lead. IN CC T Transmitter Outputs. These are RS-232 levels (nominally 10V). OUT R Receiver Inputs. These inputs accept RS-232 input levels. An internal 5k pull-down resistor to GND is connected to each input. IN R Receiver Outputs. These are TTL/CMOS levels. OUT EN Enable input. This is an active low input which enables the receiver outputs. With EN = 5V, the receiver outputs are placed in a high impedance state. SD Shutdown Input. With SD = 5V, the charge pump is disabled, the receiver outputs are in a high impedance state and the transmitters are shut off. NC No Connect. No connections are made to these leads.
