SN75LPE185 General Description

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 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/ms. The driver output swing is clamped at ±6 V to enable the higher data rates associated with this device and 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 the MODE pin and a high-level input on the EN pin, 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 the MODE and EN pins, all drivers and receivers are disabled to implement the STANDBY mode. The outputs of the drivers are in a 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, or 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 0°C to 70°C.
