Typically, the SN75C185 replaces one SN75188 and two SN75189 devices. This device conforms to TIA/EIA-232-F. The drivers and receivers of the SN75C185 are similar to those of the SN75C188 and SN75C189A, respectively. The drivers have a controlled output slew rate that is limited to a maximum of 30 V/µs, and the receivers have filters that reject input noise pulses that are shorter than 1 µs. Both these features eliminate the need for external components. The SN75C18...
