† 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.
DescriptionThe 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.
