descriptionThe 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/m s, and the receivers have
filters that reject input noise pulses that are shorter than 1 m s. 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. By using
sampling, such peripheral devices usually are 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.
