description
The SN75C198 is a monolithic low-power BI-MOS device containing four low-power line drivers designed to
interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE) in conformance with the
specifications of ANSI EIA / TIA-232-E. The drivers of the SN75C198 are similar to those of the SN75C188
quadruple driver. The drivers have a controlled-output slew rate that is limited to a maximum of 30 V/µs. This
feature eliminates the need for external components.
The sleep-mode input, SM, can switch the outputs to high impedance, which avoids the transmission of
corrupted data during power-up and allows significant system power savings during data-off periods.
The SN75C198 is characterized for operation from 0°C to 70°C.
