SP208E / SP211E / SP213E Data Sheet Low Power, High ESD +5V RS-232 Transceivers General Description Features The SP208E-SP213E are enhanced transceivers intended Meets all EIA-232 and ITU V.28 specifications for use in RS-232 and V.28 serial communication. These Single +5V supply operation devices feature very low power consumption and single- 3mA typical static supply current supply operation making them ideal for space-constrained applications. MaxLinear on-board charge pump circuitry 4 x 0.1F external charge pump capacitors generates fully compliant RS-232 voltage levels using small 120kbps transmission rates and inexpensive 0.1F charge pump capacitors. External +12V and -12V supplies are not required. The SP211E and Standard SOIC and SSOP footprints SP213E feature a low-power shutdown mode, which reduces 1A shutdown mode (SP211E & SP213E) power supply drain to 1A. SP213E includes two receivers that remain active during shutdown to monitor for signal Two wake-up receivers (SP213E) activity. Tri-state / Rx enable (SP211E & SP213E) The SP208E-SP213E devices are pin-to-pin compatible with Improved ESD specifications: our previous SP208, SP211 and SP213 as well as industry- 15kV Human Body Model standard competitor devices. Driver output and receiver 15kV IEC6100-4-2 Air Discharge input pins are protected against ESD to over 15kV for both 8kV IEC6100-4-2 Contact Discharge Human Body Model and IEC61000-4-2 Air Discharge test methods. Data rates of 120kbps are guaranteed, making Table 1: Model Selection Table them compatible with high speed modems and PC remote- Device Drivers Receivers Pins access applications. Receivers also incorporate hysteresis SP208E 4 4 24 for clean reception of slow moving signals.
