description

The SN75LP185A is a low-power bipolar device containing three drivers and five receivers with 15 kV 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 SN75LP185A allows easy interconnection of the

UART and serial-port connector of the IBM PC/AT and compatibles. The SN75LP185A provides a rugged,

low-cost solution for this function with the combination of the bipolar processing and 15 kV of ESD protection.

The SN75LP185A 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. All the logic inputs can accept 3.3-V or 5-V input signals.

The SN75LP185A complies with the requirements of TIA/EIA-232-F and ITU V.28. 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 SN75LP185A support rates up to 256 kbit/s.

The SN75LP185A is characterized for operation from 0°C to 70°C.
