SN75C198 is a quadruple low-power line driver that meets the specifications of ANSI EIA/TIA-232-E and ITU Recommendation V.28. It has very low supply current and ultra-low supply current, and is an improved functional replacement for SN75188, Motorola MC1488, National Semiconductor DS14C88, and DS1488. It has CMOS- and TTL-compatible data inputs, with a controlled-output slew rate of 30 V/µs and an output current limit of 10 mA. It is characterized for operation from 0°C to 70°C.
The SN75C198 is a monolithic BI-MOS device containing four low-power line drivers designed to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). It complies with ANSI EIA/TIA-232-E and ITU Recommendation V.28 specifications.
| Supply Voltage Range (Vcc+) | +4.5 V to +15 V |
|---|---|
| Operating Temperature Range | 0°C to 70°C |
| Output Slew Rate Limit | 30 V/s |
| Output Current Limit | 10 mA Typ |
It is designed to interface in conformance with ANSI EIA/TIA-232-E and ITU Recommendation V.28.
The sleep-mode input can switch the outputs to a high impedance state to avoid corrupted data transmission during power-up.
