Both devices have one transmitter and one receiver. The transceivers have a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V sup- ply with a single inverting charge pump. These devices require only three 0.1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compati- ble output levels. The MAX3311 features a 1µA shutdown mode. In shut- down the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled. The MAX3313 features an INVALID output that asserts high when an active RS-232 cable signal is connected, sig- naling to the host that a peripheral is connected to the communication port. ________________________Applications Digital Cameras PDAs GPS POS Telecommunications Handy Terminals Set-Top Boxes Features  1µA Low-Power Shutdown (MAX3311)  INVALID Output (MAX3313)  Receiver Active in Shutdown (MAX3311)  Single Transceiver (1Tx/1Rx) in 10-Pin µMAX  RS-232-Compatible Operation M A X 3 3 1 1 /M A X 3 3 1 3 460kbps, 1µA Supply Current, RS-232-Compatible Transceivers in µMAX ________________________________________________________________ Maxim Integrated Products 1 Pin Configurations 19-1901; Rev 0; 2/01 Ordering Information PART TEMP.

M A X 3 3 1 1 /M A X 3 3 1 3 460kbps, 1µA Supply Current, RS-232-Compatible Transceivers in µMAX _______________________________________________________________________________________ 5 Detailed Description Single Charge-Pump Voltage Converter The MAX3311/MAX3313 internal power supply has a single inverting charge pump that provides a negative voltage from a single +5V supply. The charge pump operates in a discontinuous mode and requires a flying capacitor (C1) and a reservoir capacitor (C2) to gener- ate the V- supply. RS-232-Compatible Driver The transmitter is an inverting level translator that con- verts CMOS-logic levels to EIA/TIA-232-compatible lev- els. It guarantees data rates up to 460kbps with worst-case loads of 3kΩ in parallel with 1000pF. When SHDN is driven low, the transmitter is disabled and put into three state. The transmitter input does not have an internal pullup resistor. RS-232 Receiver The MAX3311/MAX3313 receiver converts RS-232 sig- nals to CMOS-logic output levels. The MAX3311 receiv- er will remain active during shutdown mode. The MAX3313 INVALID indicates when an RS-232 signal is present at the receiver input, and therefore when the port is in use. The MAX3313 INVALID output is pulled low when no valid RS-232 signal level is detected on the receiver input. MAX3311 Shutdown Mode In shutdown mode, the charge pump is turned off, V- is pulled to ground, and the transmitter output is disabled (Table 1). This reduces supply current typically to 1µA. The time required to exit shutdown is typically less than 100µs. Applications Information Capacitor Selection The capacitor type used for C1 and C2 is not critical for proper operation; either polarized or nonpolarized capacitors are acceptable. If polarized capacitors are used, connect polarity as shown in the Typical Operating Circuit. The charge pump requires 0.1µF capacitors. Increasing the capacitor values (e.g., by a factor of 2) reduces power consumption. C2 can be increased without changing C1’s value. However, do not increase C1’s value without also increasing the value of C2 and CBYPASS to maintain the proper ratios (C1 to the other capacitors). When using the minimum 0.1µF capacitors, make sure the capacitance does not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor’s equivalent series resis- tance (ESR) usually rises at low temperatures and influ- ences the amount of ripple on V-. To reduce the output impedance at V-, use larger capacitors (up to 10µF). Bypass VCC to ground with at least 0.1µF. In applica- tions sensitive to power-supply noise generated by the charge pump, decouple VCC to ground with a capaci- tor the same size as (or larger than) charge-pump capacitors C1 and C2. Transmitter Output when Exiting Shutdown Figure 1 shows the transmitter output when exiting shutdown mode. The transmitter is loaded with 3kΩ in parallel with 1000pF. The transmitter output displays no ringing or undesirable transients as the MAX3311 comes out of shutdown. Note that the transmitter is enabled only when the magnitude of V- exceeds approximately -3V. Table 1.
