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. FUNCTION TABLE INPUTS SM A B OUTPUT Y HHH L HLX H...
