SLLS065D - AUGUST 1989 - REVISED MARCH 1997
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). The SN75C185 will typically replace one SN75188 and two SN75189 devices. This device is designed to conform to ANSI Standards EIA/TIA-232-E. The three drivers and five receivers of the SN75C185 are similar to those of the SN75C188 quad drivers and SN75C189A quad receivers, 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 has been designed using low-power techniques in a BiMOS technology. In most applications, the receivers contained in this device will interface to single inputs of peripheral devices such as ACEs, UARTS, or micro-processors. By using sampling, such peripheral devices are usually insensitive to the transition times of the input signals. If this is not the case, or for other uses, it is recommended that the SN75C185 receiver outputs be buffered by single Schmitt input gates or single gates of the HCMOS, ALS, or 74F logic families.
The SN75C185 is characterized for operation from 0°C to 70°C.
