The SN75C185 is a low-power BiMOS device containing three independent drivers and five receivers that are used to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). 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/us, and the receivers have filters that reject input noise pulses that are shorter than 1 us. Both these features eliminate the need for external components.
The SN75C185 uses the low-power BiMOS technology. In most applications, the receivers contained in this device interface to single inputs of peripheral devices such as ACEs, UARTS, or microprocessors.
