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/µs. 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
