The SN75LPE185 is a low-power bipolar device containing three drivers and five receivers, with 15-kV ESD protection on the bus pins, with respect to each other. Bus pins are defined as those pins that tie directly to the serial-port connector, including GND. The pinout matches the flow-through design of the industry-standard SN75185, SN75C185, and SN75LP185, with the addition of four pins for control signals. The flow-through pinout of the device allows easy interconnection of the universal asynchronous receiver/transmitter (UART) and serial-port connector of the IBM PC compatibles. The SN75LPE185 provides a rugged, low-cost solution for this function, with the combination of bipolar processing and 15-kV ESD protection. The SN75LPE185 has an internal slew-rate control to provide a maximum rate of change in the output signal of 30 V/us. The driver output swing is clamped at 6 V to enable the higher data rates associated with this device and to reduce EMI emissions. Although the driver outputs are clamped, the outputs can handle voltages up to 15 V without damage. The device has flexible control options for power management when the serial port is inactive. A common disable for all of the drivers and receivers is provided with the active-low enable (EN\) input. The mode-control (MODE) input selects between the STANDBY and WAKE-UP modes. With a low-level input on MODE and a high-level input on EN\, one receiver remains active, while the remaining drivers and receivers are disabled to implement the WAKE-UP mode. With a high-level input on both MODE and EN\, all drivers and receivers are disabled to implement the STANDBY mode. The outputs of the drivers are in the high-impedance state when the device is powered off. To ensure the outputs of the receivers are in a known output level (as listed in the Application Information section of this data sheet) when the device is powered off, in STANDBY mode, or in WAKE-UP mode, external pullup/pulldown circuitry must be provided. All the logic inputs accept 3.3-V or 5-V input signals. The SN75LPE185 complies with the requirements of TIA/EIA-232-F and ITU v.28 standards. These standards are for data interchange between a host computer and peripheral at signaling rates up to 20 kbit/s. The switching speeds of the SN75LPE185 support rates up to 256 kbit/s. The SN75LPE185 is characterized for operation from 0C to 70C.
