description  
The SN75LBC187 is a low-power LinBiCMOS device containing three drivers, five receivers, and a  
switched-capacitor voltage converter. The SN75LBC187 provides a single chip and single 5-V supply interface  
between the asynchronous communications element and the serial port connector of the data terminal  
equipment (DTE). This device has been designed to conform to ANSI Standards EIA/TIA-232-E, EIA/TIA-562,  
and ITU recommendation V.28.  
The switched-capacitor voltage converter of the SN75LBC187 uses four small external capacitors to generate  
the positive and negative voltages required by EIA/TIA-232-E (and V.28) line drivers from a single 5-V input.  
The drivers feature output slew-rate limiting to eliminate the need for external filter capacitors. The receivers  
can accept ±30 V without damage. The device also features a reduced power or shutdown mode that cuts the  
quiescent power to the IC when not transmitting data between the CPU and peripheral.  
The SN75LBC187 has been designed using LinBiCMOS technology and cells contained in the Texas  
Instruments LinASIC library. The SN75LBC187 is characterized for operation from 0°C to 70°C.  
NOTE:  
This device includes circuit designs and process technologies that have patents pending.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specifications per the terms of Texas Instruments  
standard warranty. Production processing does not necessarily include  
testing of all parameters.
