description
The MC1488, SN55188, and SN75188 are
monolithic quadruple line drivers designed to
interface data terminal equipment with data
communications equipment in conformance with
ANSI EIA/TIA-232-E using a diode in series with
each supply-voltage terminal as shown under
typical applications.
The SN55188 is characterized for operation over
the full military temperature range of – 55°C to
125°C. The MC1488 and SN75188 are
characterized for operation from 0°C to 70°C.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to the network ground terminal.
2. For operation above 25°C free-air temperature, refer to the maximum supply voltage curve, Figure 6. In the FK and J packages,
SN55188 chips are alloy mounted.
