Description

The SN75C185N is a low-power BiMOS Driver and Receiver 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 driver has a controlled output slew rate that is limited to a maximum of 30V/µs and the receiver has filters that reject input noise pulses that are shorter than 1µs. It features eliminate the need for external components. In most applications, the receiver contained in this device interface to single inputs of peripheral devices such as ACEs, UARTS or microprocessors.
