ICL3207CA

Datasheet ICL3207 Low Power, +3V to +5.5V, 250kbps, RS-232 Transmitter/Receiver The ICL3207 is a 3.0V to 5.5V powered RS-232 transmitter/receiver that meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. The ICL3207 features five transmitters and three receivers. Targeted applications are ISDN Terminal Adapters (TAs), PDAs, Palmtops, peripherals, and notebook and laptop computers where the low operational power and even lower standby power consumption is critical. Small footprint packaging and the use of small, low value capacitors ensure board space savings. Data rates greater than 250kbps are ensured at worst case load conditions. The ICL3207 is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. The ICL3207 is a lower power, pin-for-pin replacement for the MAX207, HIN207, and HIN237. Table 1 summarizes the features of the ICL3207. AN9863 summarizes the features of each device in the ICL32xx 3V family.

Application Information Application Information The ICL3207 operates from a single +3V to +5.5V power supply, ensures a 250kbps minimum data rate, requires only four small external 0.1µF capacitors, features low power consumption, and meets all ElA RS-232C and V.28 specifications. 4.1 Charge Pump The ICL3207 uses regulated on-chip dual charge pumps as voltage doublers. It uses voltage inverters to generate ±5.5V transmitter supplies from a VCC supply as low as 3.0V. The charge pumps allow the ICL3207 to maintain RS-232 compliant output levels over the ±10% tolerance range of 3.3V powered systems. The efficient on-chip power supplies require only four small, external 0.1µF capacitors for the voltage doubler and inverter functions at VCC = 3.3V. See “Capacitor Selection” on page 10 and Table 5 on page 10 for capacitor recommendations for other operating conditions. The charge pumps operate discontinuously (turning off as soon as the V+ and Vsupplies are pumped up to the nominal values) and provide significant power savings. 4.1.1 Charge Pump Abs Max Ratings The ICL3207 is fully characterized for 3.0V to 3.6V operation, and at critical points for 4.5V to 5.5V operation. Furthermore, load conditions were favorable using static logic states only. The specified maximum values for V+ and V- are +7V and -7V, respectively. These limits apply for VCC values set to 3.0V and 3.6V (see Table 2). For VCC values set to 4.5V and 5.5V, the maximum values for V+ and V- can approach +9V and -7V, respectively (see Table 3 on page 9). The breakdown characteristics for V+ and V- were measured with ±13V. Table 2.

Table 4. 4.2 New Measured Withstanding Voltages V+, V- to Ground ±13V V+ to V- 20V Transmitters The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-232 output levels. The transmitters are coupled with the on-chip ±5.5V supplies to deliver true RS-232 levels across a wide range of single supply system voltages. The ICL3207 ensures a 250kbps data rate for full load conditions (3kΩ and 1000pF), VCC ≥ 3.0V, with one transmitter operating at full speed. Under more typical conditions of VCC ≥ 3.3V, RL = 3kΩ, and CL = 250pF, one transmitter easily operates at 800kbps. Transmitter inputs float if they are not connected and can cause ICC to increase. Connect unused inputs to GND for the best performance. FN4892 Rev.8.00 May.16.19 Page 9 of 17 ICL3207 4.3 4. Application Information Receivers The ICL3207 has inverting receivers that convert RS-232 signals to CMOS output levels and accept inputs up to ±25V while presenting the required 3kΩ to 7kΩ input impedance (see Figure 5) even if the power is off (VCC = 0V). The receivers’ Schmitt trigger input stage uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions. Receivers on the ICL3207 are always active. VCC RXIN -25V ≤ VRIN ≤ +25V RXOUT 5kΩ GND ≤ VROUT ≤ VCC GND Figure 5. Inverting Receiver Connections 4.4 Low Power Operation The 3V ICL3207 requires a nominal supply current of 0.3mA, even at VCC = 5.5V, during normal operation. This supply current is considerably less than the 11mA current required by comparable 5V RS-232 devices and allows you to reduce system power by replacing the old style device with the ICL3207. 4.4.1 Low Power, Pin Compatible Replacement Pin compatibility with existing 5V products (such as the MAX207), coupled with the wide operating supply range, makes the ICL3207 a potential lower power, higher performance drop-in replacement for existing 5V applications. As long as the ±5V RS-232 output swings are acceptable, the ICL3207 works in most 5V applications. When replacing a device in an existing 5V application, it is acceptable to terminate C3 to VCC as shown in the “Typical Operating Circuit” on page 3. Terminate C3 to GND if possible, as slightly better performance results from this configuration. 4.5 Capacitor Selection The charge pumps require 0.1µF or greater capacitors for 3.3V operation. With 0.1µF capacitors, 5% tolerance supplies (3.14V minimum) deliver greater than ±5V transmitter swings at full data rate. 10% tolerance supplies (2.97V minimum) deliver ±4.95V transmitter swings. If greater than ±5V transmitter swings are required with a 10% tolerance 3.3V supply, 0.22µF capacitors are recommended (see Table 5). Existing 5V applications typically use either 0.1µF or 1µF capacitors, and the ICL3207 works well with either value. New 5V designs should use 0.22µF capacitors for the best results. For other supply voltages, see Table 5 for capacitor values. Do not use values smaller than those listed in Table 5. Increasing the capacitor values (by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without increasing C1’s value; however, do not increase C1 without also increasing C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors). When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor’s Equivalent Series Resistance (ESR) usually rises at low temperatures and influences the amount of ripple on V+ and V-. Table 5. Required Capacitor Values VCC (V) C1 (µF) C2, C3, C4 (µF) 3.15 to 3.6 0.1 0.1 3.0 to 3.6 0.22 0.22 4.5 to 5.5 0.1 to 1.0 0.1 to 1.0 3.0 to 5.5 0.22 0.22 FN4892 Rev.8.00 May.16.19 Page 10 of 17 ICL3207 4.6 4. Application Information Power Supply Decoupling In most circumstances, a 0.1µF bypass capacitor is adequate. In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge pump capacitor C1. Connect the bypass capacitor as close as possible to the IC. 4.7 High Data Rates The ICL3207 maintains the RS-232 ±5V minimum transmitter output voltages even at high data rates. Figure 6 shows a transmitter loopback test circuit, and Figure 7 illustrates the loopback test result at 120kbps. For this test, all transmitters were simultaneously driving RS-232 loads in parallel with 1000pF, at 120kbps. Figure 8 shows the loopback results for a single transmitter driving 1000pF and an RS-232 load at 250kbps. The static transmitters were also loaded with an RS-232 receiver.
