HIN232, HIN236, HIN237, HIN238, HIN239, HIN240, HIN241 ® Data Sheet September 26, 2008 FN3138.16 +5V Powered RS-232 Transmitters/Receivers Features The HIN232-HIN241 family of RS-232 transmitters/receivers interface circuits meet all ElA RS-232E and V.28 specifications, and are particularly suited for those applications where ±12V is not available. They require a single +5V power supply (except HIN239) and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The family of devices offer a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications (see “Selection Table” on page 1). • Requires Only Single +5V Power Supply - (+5V and +12V - HIN239) The drivers feature true TTL/CMOS input compatibility, slew-rate-limited output, and 300Ω power-off source impedance. The receivers can handle up to ±30V, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection. • Multiple Drivers - ±10V Output Swing for 5V lnput - 300Ω Power-Off Source Impedance - Output Current Limiting - TTL/CMOS Compatible - 30V/µs Maximum Slew Rate • Meets All RS-232E and V.28 Specifications • High Data Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . 120kbps • Onboard Voltage Doubler/Inverter • Low Power Consumption • Low Power Shutdown Function • Three-State TTL/CMOS Receiver Outputs • Multiple Receivers - ±30V Input Voltage Range - 3kΩ to 7kΩ 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 POWER SUPPLY VOLTAGE NUMBER OF RS-232 DRIVERS NUMBER OF RS-232 RECEIVERS EXTERNAL COMPONENTS LOW POWER SHUTDOWN/TTL THREE-STATE NUMBER OF 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 PART NUMBER 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.

CHARGE PUMP Detailed Description The HIN232 thru HIN241 family of RS-232 transmitters/receivers are powered by a single +5V power supply (except HIN239), feature low power consumption, and meet all ElA RS-232C and V.28 specifications. The circuit is divided into three sections: The charge pump, transmitter, and receiver. Charge Pump An equivalent circuit of the charge pump is illustrated in Figure 1. The charge pump contains two sections: the voltage doubler and the voltage inverter. Each section is driven by a two-phase, internally generated clock to generate +10V and -10V. The nominal clock frequency is 16kHz. During phase one of the clock, capacitor C1 is charged to VCC . During phase two, the voltage on C1 is added to VCC , producing a signal across C3 equal to twice VCC . During phase one, C2 is also charged to 2VCC , and then during phase two, it is 10 inverted with respect to ground to produce a signal across C4 equal to -2VCC . The charge pump accepts input voltages up to 5.5V. The output impedance of the voltage doubler section (V+) is approximately 200Ω, and the output impedance of the voltage inverter section (V-) is approximately 450Ω. A typical application uses 1µF capacitors for C1-C4, however, the value is not critical. Increasing the values of C1 and C2 will lower the output impedance of the voltage doubler and inverter, increasing the values of the reservoir capacitors, C3 and C4, lowers the ripple on the V+ and V- supplies. During shutdown mode (HIN236, HIN240 and HIN241), SHUTDOWN control line set to logic “1”, the charge pump is turned off, V+ is pulled down to VCC , V- is pulled up to GND, and the supply current is reduced to less than 10µA. The transmitter outputs are disabled and the receiver outputs are placed in the high impedance state. FN3138.16 September 26, 2008 HIN232, HIN236, HIN237, HIN238, HIN239, HIN240, HIN241 Transmitters Receivers The transmitters are TTL/CMOS compatible inverters which translate the inputs to RS-232 outputs. The input logic threshold is about 26% of VCC , or 1.3V for VCC = 5V. A logic 1 at the input results in a voltage of between -5V and V- at the output, and a logic 0 results in a voltage between +5V and (V+ -0.6V). Each transmitter input has an internal 400kΩ pullup resistor so any unused input can be left unconnected and its output remains in its low state. The output voltage swing meets the RS-232C specifications of ±5V minimum with the worst case conditions of: all transmitters driving 3kΩ minimum load impedance, VCC = 4.5V, and maximum allowable operating temperature. The transmitters have an internally limited output slew rate which is less than 30V/µs. The outputs are short circuit protected and can be shorted to ground indefinitely. The powered down output impedance is a minimum of 300Ω with ±2V applied to the outputs and VCC = 0V. The receiver inputs accept up to ±30V while presenting the required 3kΩ to 7kΩ input impedance even if the power is off (VCC = 0V). The receivers have a typical input threshold of 1.3V which is within the ±3V limits, known as the transition region, of the RS-232 specifications. The receiver output is 0V to VCC . The output will be low whenever the input is greater than 2.4V and high whenever the input is floating or driven between +0.8V and -30V. The receivers feature 0.5V hysteresis to improve noise rejection. The receiver Enable line EN, when set to logic “1”, (HIN236, HIN239, HIN240, and HIN241) disables the receiver outputs, placing them in the high impedance mode. The receiver outputs are also placed in the high impedance state when in shutdown mode.

The benefit of sharing common reservoir capacitors is the elimination of two capacitors and the reduction of the charge pump source impedance which effectively increases the output swing of the transmitters.
