SN75LP1185
description
The SN75LP1185 is a low-power bipolar device containing three drivers and five receivers, with 15 k V of 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 and SN75C185. The flow-through pinout of the SN75LP1185 allows easy interconnection of the UART and serial-port connector of the IBM PC/AT and patibles. The SN75LP1185 provides a rugged, low-cost solution for this function with the bination of the bipolar processing and 15 k V of ESD protection.
The SN75LP1185 has internal slew-rate control to provide a maximum rate of change in the output signal of 30 V/µs. The driver output swing is nominally clamped at ±6 V to enable the higher data rates associated with this device and to reduce EMI emissions. Even though the driver outputs are clamped, they can handle voltages up to ±15 V without damage....
